Purchased at the Stationery Girls' Expo 2025 Yokohama. It's the Antibacterial Clear L memo cover with a pocket. It also has a pen holder, which is convenient. The ring part on the back of the cover has holes, which is what you'd expect from a dedicated product. The height doesn't match the rings of my other notebooks, so it's specifically for Rollbahn notebooks. If purchased with other items, I'll give you a 200 yen discount. I'll fold it gently at the ring part and ship it in an envelope via anonymous Nekopos delivery.
