Bikkuriman Sleeves Collection Sleeves Available in separate listings, from 50 to 500 pieces. If you need more than that, please comment. For 48mm square, used to protect collection stickers. These are hard sleeves, not soft, so they provide even stronger protection against scratches to the stickers. I've made various types, and this thickness is the most suitable. If they're made thinner, they feel flimsy, and if they're thicker, the transparency is compromised, so I settled on this. Regarding refills, I've received many questions, so I'll explain. 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, and the 12-pocket is for 52mm square. (For single sleeves) The 20-pocket can hold 240 stickers, and the 12-pocket can hold 144 stickers. I use 12-pocket for old Bikkuriman with double sleeves and Bikkuriman 2000 with single sleeves to standardize the refill size. I think the 12-pocket is suitable for old Bikkuriman because the arrangement looks good. There are various types of refills, some where the stickers fall out easily when turned upside down, and some that are thin and flimsy, but the YSV-BDH81 refill is definitely a good choice. If you want even stronger protection, I also sell 52mm square sleeves in a separate listing. You can put the 52mm square sleeves over the 48mm square sleeves. How about perfect protection with double sleeves? 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 only, 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 want Mercari shipping, please comment separately.
