1. After some research, it seems to be from the "BOP" series. 2. I believe it's rare as there are no listings of the same color on Mercari. 3. It came from my child's room. It's probably very clean, so I think it's unused. There are no peeling, stickiness, or stains. 4. How about using it daily or for your collection? ◯【Product Information】 Product Condition: Probably unused Product Status: Clean Storage: Home Size (approx. cm): 17 x 12 x 6 ◯【Notes/Other】 ・I inspect the items thoroughly before listing to ensure there are no problems, but since they are stored at home, both new and used items may have some minor scratches or stains. ・To ensure a pleasant transaction for both parties, I will provide detailed product information, so please review it. ・Please note that the color may appear slightly different from the actual item due to the lighting during photography. ・I will consider discounts and combined purchases within a reasonable range, so please contact me. ◯【Shipping】 There are Yamato Transport and 7-Eleven nearby. I will use simple packaging for items that won't break, and I will perfectly package fragile items, shipping them within the same day or the day after the next.
