Bikkuriman Sleeve Sleeves for collection I am selling from 50 to 500 pieces in separate listings. If you need more than that, please comment. For 52mm square, storage bag for protecting collection seals. 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 was the most suitable ^ ^ If I make them thinner, they feel flimsy, and if I make them thicker, the transparency is compromised, so I settled on this. I will address the inquiries about refills, as I've received many questions. For refills, search for "R YSV-BDH81 pocket refill". I also use them ^ ^ 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 12-pocket for old Bikkuriman cards with double sleeves and Bikkuriman 2000 cards with single sleeves to standardize the refill size. I think the 12-pocket is suitable for old Bikkuriman cards as they look better when arranged. There are various types of refills, some where the cards fall out easily when turned upside down, and some that are thin and flimsy, so the YSV-BDH81 refill is the best choice. Made in Japan, but due to the machine specifications, there may be some dimensional errors, so please understand. Shipping Standard mail, simple packaging. For 100 pieces, I will divide them into two bags by eye (e.g., 40 pieces and 60 pieces), so the distribution will be uneven. Please understand. If you prefer Mercari shipping, please comment separately.
