Overview
Japan offers a wide range of Gunpla, including:
The main buying mistake is comparing listings by mobile-suit name alone.
Two kits with the same Gundam name can be completely different products.
- standard retail HG kits
- RG
- MG
- PG
- Premium Bandai releases
- event exclusives
- older kits
- limited color variants
Identify the exact kit
Confirm:
Package art and product codes are often more useful than a translated title.
- grade
- scale
- product name
- product code
- release
- standard vs. limited edition
- Premium Bandai status
- special-color or event version
Unbuilt condition is the key question for used kits
Useful Japanese terms:
For used kits, confirm whether the runners and inner bags are complete.
A closed outer box does not prove the runners are untouched.
- 未組立 — unassembled
- 未開封 — unopened
- 内袋未開封 — inner bags unopened
- 組立済み — assembled
- 一部組立 — partially assembled
- 欠品 — missing parts
- ジャンク — junk/as-is
Check runners, decals, and instructions
Look for:
For a limited kit, one missing runner can matter more than cosmetic box wear.
- missing runners
- clipped parts
- loose pieces
- missing polycaps
- missing decals
- missing stickers
- missing manual
- water damage
- box crushing
Premium Bandai and limited releases
Verify:
Do not compare a standard retail kit directly with a limited P-Bandai version simply because the base mobile suit is the same.
- exact product name
- P-Bandai status
- color
- expansion parts
- included weapons
- release period
- packaging

Box condition vs. build condition
Collectors may care about the retail box.
Builders may mainly care that all runners are present.
Before buying, decide whether:
Do not pay collector pricing for box condition you do not need.
- box crushing is acceptable
- sealed inner bags matter
- retailer stickers matter
- collector packaging matters
Shipping cost is often driven by volume
Gunpla is usually light for its size.
Several MG or PG boxes can create a large parcel with significant dimensional weight.
Before consolidating:
- check final dimensions
- compare one large parcel with split shipments
- preserve retail boxes only where needed
- protect smaller kits from heavy items
