Here's a collection of washi origami paper. * 15cm square: 4 sets * 10cm square: 2 sets Only the ribbon-themed origami is unopened. The other items are not unopened. The origami with the Showa-era retro characters in photo 6 is the type where the picture disappears when heat is applied? *In reality, the picture fades slightly.* Since there are few sheets, this will be included as a bonus. All items are over 30 years old, so there may be paper-specific odors and creases (as shown in photo 5). There may also be oversights. Please understand that there may be scratches and stains before purchasing. I will package them to prevent them from getting wet and ship them.
