バインダー用インサート - 3ポケットスリーブ（5枚セット）

The flaps on these inserts are a game-changer—no more stickers sliding out when I flip through my binder. The three pockets per sleeve give me just the right amount of space for my small collection.

Finally, a sleeve that actually holds multiple sticker sheets without them sliding out. The three pockets with flaps are a lifesaver, and the clear plastic lets me see what's inside at a glance.

The flaps keep my sticker sheets from sliding around when I flip through the binder, which was a constant annoyance with my old sleeves. Each insert holds three different-sized pages without any bulging. Exactly what I needed for my growing collection.
