Bikkuriman Sleeves Collection Sleeves Available in separate listings, from 50 to 500 sleeves. If you need more than that, please comment. For 48mm square cards, these are storage bags for protecting your collection's 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 was the most suitable. If I made them thinner, they would feel flimsy, and if I made them thicker, the transparency would be compromised, so I settled on this. Regarding the 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 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), standardizing the refill size. I think the 12-pocket is suitable for old Bikkuriman cards because of the layout. 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 refills are reliable. For those who want even stronger protection, I am selling 52mm square sleeves in a separate listing. You can also 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 orders of 100 sleeves, I will divide them into two bags by eye (e.g., 40 and 60), so the distribution will be uneven. Please understand. If you prefer Mercari shipping, please comment separately.
