Because Gundam is one of the most collected franchises, it is also one of the most copied. This guide walks through the checks collectors commonly use to evaluate authenticity and condition — the same points our staff in Japan look at when inspecting every item before it ships.
Official Markings and Licensing Indicators
On authentic Gundam action figures — whether from the Robot Damashii, Gundam Fix Figuration, Metal Robot Spirits, or Mobile Suit in Action (MSiA) lines — collectors commonly look for clearly molded or printed copyright text such as ©SOTSU and ©SUNRISE, often accompanied by the Bandai or Bandai Spirits logo. This marking is usually found on the sole of a foot, the inside of a skirt armor piece, or on the back of the torso, and on genuine pieces the text is typically crisp, evenly spaced, and consistent in depth.
Boxes and inner trays on authentic items generally carry a Bandai/Bandai Spirits barcode, a country-of-manufacture line (often ‘Made in China’ or ‘Made in Vietnam’ for recent releases), and, for Japan-market releases, Japanese-language safety and age warnings. A missing copyright block, blurred logos, or English-only text on what should be a domestic Japanese release is often a useful signal to look more closely.
Packaging and Print Quality
Genuine Gundam figure packaging is commonly a sturdy, glossy-finished box with sharp four-color printing, deep blacks, and cleanly registered line art of the mobile suit. Windowed boxes (typical of Robot Damashii and Metal Robot Spirits) usually use clear PET with a clean bend along the fold, and the inner blister tray is generally a well-fitted vacuum-formed insert with cutouts shaped precisely to each accessory. Instruction sheets on authentic pieces are often printed on smooth, thin paper with legible Japanese text and small legal print at the bottom.
Common warning signs include fuzzy or pixelated logos, off-color box art (Gundam red or Char pink appearing muted or overly orange), misaligned printing on the spine, and thin or flimsy cardboard. Reused generic trays that do not match the figure’s silhouette are also frequently seen on unofficial reproductions.
Paint, Seams, and Material Tells
On authentic Bandai Gundam figures, the plastic commonly has a slightly satin finish rather than a cheap high-gloss shine, and multi-color parts (such as the V-fin, chest vents, or shoulder verniers) are usually achieved with separately molded pieces rather than sloppy hand-painted overlays. Panel lines and tampo-printed markings — unit numbers, warning stencils, and the Earth Federation or Zeon insignia — are generally sharp and correctly positioned. Joints on genuine pieces typically feel firm but smooth, with die-cast parts (in Metal Robot Spirits or GFF Metal Composite) having a noticeable weight.
Red flags often include greasy or brittle plastic, visible mold flash along seams, misaligned two-tone parts, crooked tampo prints, and joints that either flop loosely or feel gritty. Chrome or metallic finishes that flake easily, or gold parts that look yellow-green rather than warm gold, are also frequently reported on non-genuine copies.
Common Bootleg Red Flags in the Gundam Line
Because Gundam is one of the most widely copied franchises, unofficial versions are often encountered — particularly of popular suits like the RX-78-2, Nu Gundam, Sazabi, Unicorn, and Barbatos. Bootlegs commonly arrive in plain white boxes, in boxes labeled only with generic terms like ‘Gundam Robot’ without Bandai branding, or in packaging that mixes artwork from multiple official releases. Bundled ‘bonus’ effect parts or extra weapons not shown in official product photos can also be a useful signal to verify the source.
Price is another practical indicator: a sealed Metal Robot Spirits or GFFMC figure listed far below typical Japanese secondary-market prices is often too good to be true. Sellers unable to show the copyright stamp, the runner/tray, or the instruction booklet on request may also warrant caution. None of these signs alone confirms a fake, but several appearing together generally justifies a closer look.
Japanese Secondhand Condition Grading
Japanese resellers commonly use a tiered grading system that collectors should understand before buying. Unopened / 未開封 means the box is factory-sealed, though outer sleeve wear may still be noted. Grade A typically indicates an opened item in excellent condition — all parts and accessories present, minimal display wear, and box in clean shape. Grade B often means noticeable play or display wear: minor paint rubs, slightly loose joints, some yellowing on white plastic, or a creased box. Grade C generally signals significant wear, possible missing minor accessories, or heavier scuffs.
Junk / ジャンク is usually reserved for incomplete, damaged, or non-functional items — for example, missing a beam saber, broken V-fin, or no box — and is sold as-is. For Gundam figures specifically, buyers are commonly advised to check whether small accessories (hand parts, beam effects, joint adapters) are included, since these are frequently lost and heavily affect resale value.

Frequently Asked Questions
How can I tell if a Gundam figure is a bootleg?
Check the manufacturer and copyright markings moulded into the base or the back of the figure, compare paint edges and seam lines against official product photos, and look at the print quality of the box. Bootlegs usually fail on several of these at once, not just one.
Is a cheap listing automatically a fake?
No. Price on its own proves nothing — genuine pieces sell cheaply when they are opened, incomplete or from an over-produced run. Judge by markings, finish and packaging rather than by price.
What should I ask a seller for before buying?
Ask for photos of the base markings, the box barcode and any damage in natural light. A seller who handles the item themselves can take these quickly; stock-photo-only listings are the ones worth questioning.
What does Japanese secondhand condition wording mean?
Japanese listings grade strictly: a piece described as used can still be display-quality, while notes about yellowing, paint transfer or box crush are stated explicitly rather than glossed over. Read the condition notes as literal, not as sales copy.
