Hello. I am not a native Japanese speaker. I apologize if my Japanese is unnatural. This is a postcard set from Rainbow Islands Parties Party. It's unclear where this came from, but it was likely a pre-order bonus or a point-of-sale bonus. The three postcards are slightly yellowed due to aging. There is minor damage. The envelope is unused, but there are folds, etc. Please contact me if you have any questions or need additional images. Returns and refunds are not accepted. Please take a look at my other items for sale. #Bubble Bobble #Taito #Rainbow Islands #WonderSwan #BANDAI
