Stationery maker from Belgium atoma 98 x 144 size / 5mm grid Using a special ring shape and leaf holes, this is an innovative system that allows for easy page movement and addition without opening and closing the rings. Pages can be rearranged. I think it's similar to the Rollbahn Flexible! I wanted to try it out and I bought a lot, so I'm selling it. It's new, but it's from overseas, so the edges may be slightly crushed. Please purchase with your understanding!
