Bikkuriman Sleeves Collection Sleeves We also have listings for 50 to 500 sleeves in separate listings. If you need more than that, please comment. Storage bag for 48mm square. For protecting your collected stickers. These are hard sleeves, not soft, so they provide even stronger protection against scratches on your items. I've tried various thicknesses, and this one was just right. Any thinner and they feel flimsy, any thicker and the transparency is compromised, so this is where I settled. Many people have asked about refills, so I'll include that information here. For refills, please search for "YSV-BDH81 pocket refill" by R. I use them myself. 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-sleeved stickers) The 20-pocket can hold 240 stickers, and the 12-pocket can hold 144 stickers. I store my old Bikkuriman stickers in double sleeves and Bikkuriman 2000 in single sleeves, unifying the refill sizes. For old Bikkuriman, I think the 12-pocket is better for arrangement. There are various types of refills, some where the stickers fall out easily if turned upside down, and some that are thin and flimsy. The YSV-BDH81 refills are definitely good. If you want even stronger protection, I have 52mm square sleeves listed separately. You can also put a 52mm square sleeve over the 48mm square sleeve. How about perfect protection with double sleeves? These are made in Japan, but please understand that there may be slight dimensional errors due to machine specifications. Shipping Standard mail with simple packaging. For 100 sheets only, I will divide them into two bags by eye (e.g., 40 sheets and 60 sheets), so the amounts will be uneven. Please understand.
