Product Overview — A Soothing Knit Featuring the Adorable Boo

From Japan’s beloved brand Gelato Pique, this special collaboration brings together comfort and nostalgia in one charming piece.
This cardigan features Boo, one of the most popular “enemy” characters from the Super Mario series, woven throughout in full jacquard.
The fluffy texture and gentle touch feel soft even against bare skin, while the shawl collar design frames the face beautifully.
The front buttons make it easy to style open or closed, and the relaxed silhouette flatters all body types.

Another design in the same collection features a “Star” pattern — however, this version is the Boo pattern.

• Best for: working from home, relaxing weekends, or light travel — it transitions easily between indoor and outdoor wear.
• Design details: full jacquard knit / shawl collar / relaxed fit / button-front closure.

About the Jacquard Cowichan Knit

This cardigan blends two traditional techniques — jacquard knitting and Cowichan-style knitting — to create a piece that feels both classic and modern.
Gelato Pique’s signature soft yarn transforms these historic methods into something lighter, smoother, and effortlessly wearable.

What Is Jacquard Knitting?

Jacquard knitting uses multiple colored threads to weave patterns directly into the fabric, rather than printing them on the surface.
This creates dimensional, high-quality designs that stand out for their durability and texture — patterns often appear reversed on the inside, giving the garment a sense of depth and craftsmanship.

The Origins of Cowichan Knits

The “Cowichan Sweater” originated with the Cowichan people of British Columbia, Canada.
These sweaters are known for their thick wool, warmth, and hand-knit motifs such as animals and geometric shapes.
Today, their rustic charm and traditional craftsmanship are celebrated around the world as timeless fashion.

Why This Combination Works

By combining jacquard and Cowichan techniques, this cardigan achieves:

• Beautiful, three-dimensional patterns
• A balance of warmth and lightness
• A refined, vintage-inspired charm

The Boo motif’s rounded shape and gentle expression are recreated through the soft texture of the yarn, resulting in a piece that feels both playful and elegant — the very essence of Gelato Pique.

Card List by Pack

Features of the Pyrite Colosseum Stage Card

Pyrite Colosseum is a battle arena located in the desert slum town Pyrite Town, which appears early in Pokémon Colosseum.
Its rough, lawless atmosphere makes it an iconic setting closely tied to the story.

It functions as a central “battle arena” where many trainers gather to test their strength through continuous double battles.
When the Stage Card is scanned, the e-Reader+ enables these Red Pack trainer battles to be played within this Pyrite-themed stage.

※ In-game name: Deep Colosseum
※ Printed on the card: Bottom Colosseum

Features of the Bottom/Deep Colosseum Stage Card

The Deep Colosseum lies far beneath The Under, serving as an endgame, high-difficulty battle facility.
Its design features massive ventilation fans, exposed pipes, and heavy machinery—giving it the feeling of a secret industrial underworld.

Appearing only after the main story is cleared, it houses powerful trainers and bosses, leading overseas fans to call it “the hardest battles in Colosseum.”

The Stage Card recreates this intense atmosphere within the e-Reader battle mode, offering an advanced challenge for experienced players.

🟩 Green Pack（緑）

Features of the Realgam Tower Colosseum Stage Card

The Realgam Tower Colosseum is attached to the enormous tower rising from the Orre Region’s desert.
Its dazzling dome-shaped battle arena, complete with a giant Poké Ball emblem on the floor and surrounding spectator stands, establishes it as the “final battle stage” of the game.

In the main story, the tower serves as the headquarters of the villainous organization Cipher, marking the climax of Pokémon Colosseum.
Scanning this Stage Card transforms the e-Reader battle room into a dramatic, final-showdown battlefield beloved by long-time fans.

Promo-Exclusive Virtual Trainer Cards

The two cards placed at the center of the set—
Hunter BIT and Team Snagem GAKU—
are promo-only virtual trainer cards not included in any standard pack.

BIT (13-P001)

Source:Mercari

“Hunter BIT” was distributed as a bound-in bonus within the free mini-magazine Pokémon Scoop 2004 Winter, released in early 2004.
This booklet was handed out at locations such as:

• McDonald’s

• Ito-Yokado

• Toys “R” Us

• Jusco

• Daiei

• Hello Mac

• Pokémon Center stores

• World Hobby Fair (Winter 2004)

Because it was a free booklet and easily discarded, very few intact copies survive today—making BIT’s card extremely rare.

Scanning the card unlocks BIT’s special double battle in the e-Reader room.

GAKU (13-P002)

Source:Amazon

“Team Snagem GAKU” was included exclusively as a tear-out bonus item in the official Japanese strategy guide,
Pokémon Colosseum Nintendo Official Guide Book (Wonder Life Special), published by Shogakukan.

This guidebook contained three major bound-in extras:

1. Pokémon stickers

2. Type chart and data materials

3. The Double Battle e+ card: GAKU

Because only those who purchased this guidebook ever possessed the card—and many copies had the card removed—complete sets containing both the guidebook and an unused GAKU card are exceptionally rare.

How Do You Use Them? (Scanning System)

1. Scan a “Double Battle e+” card using the e-Reader+ (Card e+).

2. Connect the e-Reader+ to a Game Boy Advance (GBA).

3. Use the GBA–GameCube link cable to connect the GBA to the Nintendo GameCube.

4. When launched, Pokémon Colosseum expands, and new special double battles become available.

This three-tier system—
“Card → GBA → GameCube”—
allowed the game to evolve through physical card interaction.

Required Hardware (What You Need to Use These Cards)

To play Double Battle e+, the following equipment was required:

e-Reader+ (Card e+)

A dedicated device used to scan the e+ cards.

Game Boy Advance (GBA)

Source: Nintendo

The main hardware used to mount the e-Reader+.

Nintendo GameCube (GC)

Source: Nintendo

The console running Pokémon Colosseum.

GBA–GC Link Cable

A special cable used to connect the GBA to the GameCube.

→ Because this full setup was complex and expensive for the time, very few players actually had the complete environment, which is one major reason why today’s card population is extremely limited.

Why Is This Product Special?

• A rare system for its time: “Scanning physical cards to expand the game.”

• High entry barrier → only a small number of people ever used it.

• No overseas release → demand from international collectors is extremely high.

• Very few complete sets survive → full sets are exceptionally rare.

• Represents Nintendo’s experimental era in the early 2000s.

→ Scarcity × Uniqueness × Historical significance
make this a truly premium collector’s item.

What Is Pokémon Colosseum?

Source:Amazon

Pokémon Colosseum is a stylish and dark Pokémon RPG representing the GameCube era.
It was released on:

• November 21, 2003 (Japan)

• March 2004 (North America)

Unlike the bright, adventurous worlds typical of Pokémon at the time,
Colosseum boldly introduced a darker, more mature world—a major departure from the series’ norm.

Sales Performance: Japan & Overseas

Japan

• Approx. 340,000 units sold in the first week

• Total sales around 750,000 units

• Among the top sellers for GameCube titles

• Gained attention for being the “first full-scale Pokémon RPG on a home console”

North America / Europe

• Over 1 million units sold in North America

• Shadow Pokémon concept resonated extremely well overseas

• Widely praised as “one of the coolest Pokémon series”

• Second-hand prices continue surging in the retro market

• Rediscovered as a cult-classic title in recent years

What Kind of Game Is It?

1. A protagonist who is a former villain—an unusual premise

Source: Pokémon Official Website

The protagonist Wes is a defector from the villainous team Snagem.
His cool, shadowy persona was a huge hit among Western fans who loved more serious storytelling.

2. A story about “saving” Shadow Pokémon

The key element of Colosseum is the Shadow Pokémon concept—
Pokémon whose hearts were artificially sealed by the villain organization.

Players must:

• Snag (capture) Shadow Pokémon from enemies

• Purify them to restore their true selves

This narrative—rescuing corrupted Pokémon—became one of the series’ most dramatic storylines.

3. Every battle is a Double Battle

All main battles are 2 vs 2 double battles, providing deeper strategy and synergy.
This system influenced future Pokémon titles, helping popularize double battles in the main series.

4. Fully 3D Pokémon battles

Source: Pokémon Official Website

In 2003, real-time 3D battle animation was groundbreaking:

• Detailed attack animations

• Stylish character designs

• Cinematic camera work

Overseas fans often describe Colosseum’s visuals as “god-tier” for its era.

5. A Connected Series: Followed by Pokémon XD Gale of Darkness

The success of Colosseum led to the release of its full sequel:

Source:Amazon

Featuring:

• Expanded story

• New Shadow Pokémon

• Improved game systems

Its iconic “Shadow Lugia” remains one of the most beloved designs in Pokémon history.

Relationship to Double Battle e+

One feature that enriched Colosseum’s popularity was its expandability through the e-Reader+.

Source: Nintendo

Scanning Double Battle e+ cards allowed players to access:

• Special new trainer battles

• Stage variations

• Unique rewards

This physical-to-digital connection gave Colosseum an identity as
“the Pokémon game that evolves through real cards.”

Overseas fans often say:

“Colosseum marked Pokémon’s first step into a more mature world—
and Double Battle e+ was the secret key that expanded that world.”

Why Is This Product So Valuable?

① Extremely hard to obtain even at launch

Source: Nintendo

To use these cards, players needed:

• e-Reader+

• Game Boy Advance

• GameCube

• GBA–GC Link Cable

Because the full setup was expensive and complicated, the number of active users was extremely small.
As a result, the total print and survival rate of the cards is exceptionally low.

② Very few mint-condition cards remain

Because the cards are made of paper, they are prone to:

• bending

• surface scratches

• scanning marks

Finding clean, unused, or lightly used cards is extremely difficult.

③ A full complete set has “miracle-level” rarity

Collectors consider complete sets to be the highest tier of rarity,
and overseas buyers actively search for them.

④ Overseas re-evaluation is booming (especially in North America)　

Source:Amazon

While Pokémon Colosseum has strong global popularity,
the e-Reader system was discontinued early overseas.
This means the Double Battle e+ cards never released outside Japan,
making them “phantom extra content” for Western players.

This exclusivity has caused demand—and prices—to surge rapidly.

⑤ Boost from the retro gaming boom

Recent trends:

• Nintendo retro boom

• Renewed attention on GameCube titles

• Rising interest in obscure physical add-ons

All of these contribute to the growing demand for this product.
