HG Mobile Suit Gundam Wing: Endless Waltz Underlay (Not for Sale) Bandai Card It is the size of a standard underlay. B5 size. I don't know why I have it, but it's over 20 years old. Please look at the photos and only purchase if you understand that it is a home-stored item and has age-related deterioration. Immediate purchase OK. Price negotiation not possible (negotiable for bundled purchases if the price reduction is not significant. If someone purchases immediately before the bundle function is finalized, it may not be possible to bundle, so please forgive me in that case.) It will be shipped anonymously with a backing sheet and plastic packaging.
