Sleeved immediately after purchase. Stored in a file. Since the initial Bikkuriman cards are old, please assume they are generally in good condition at best. All cards are sleeved and will be shipped with measures to prevent water damage and bending. I also have Bikkuriman and Pokemon cards for sale, so please take a look. If you purchase 4 Bikkuriman items, I will include them in a Bikkuriman sticker binder as a service.
