Bikkuriman Sleeve Sleeves for collection We are selling from 50 to 500 sleeves in separate listings. If you need more than that, please comment. For 52mm square cards. Protective sleeves for collecting stickers. These are hard sleeves, not soft, so they provide even stronger protection against scratches to the cards. I've made various types, but this thickness is just right. If I make them thinner, they feel flimsy, and if I make them thicker, the transparency is compromised, so I settled on this. Regarding the refills, I've received many questions, so I'll explain. For refills, search for "YSV-BDH81 pocket refill" on R. I use them too ^ ^ There are two types: 20-pocket and 12-pocket. The 20-pocket is for 42mm square cards, and the 12-pocket is for 52mm square cards. (For single-sleeved cards) The 20-pocket can hold 240 cards, and the 12-pocket can hold 144 cards. I use the 12-pocket for old Bikkuriman cards (double-sleeved) and Bikkuriman 2000 cards (single-sleeved) to standardize the refill size. I think the 12-pocket is suitable for old Bikkuriman cards because the arrangement looks good. There are various types of refills, and some stickers fall out easily when turned upside down, or they are thin and flimsy, so the YSV-BDH81 refill is definitely recommended. Made in Japan, but due to the machine specifications, there may be some dimensional errors, so please understand. Shipping Mercari shipping, simple packaging.
