Yudaeng, a Korean manufacturer, Pastel Color Pouch Binder A5 size, mint. It has been used, so there are a few scratches that are difficult to see in the photos. I was using it to store collage materials, but I'm giving it away because I'm no longer doing collages. Compared to similar products from Daiso, the ring diameter is slightly larger, so I think it can hold more sheets. Retail price: 850 yen Since it's from a Korean shop, it cost a lot for shipping when I bought it new. If you'd like to try a used one, please consider it.
