This is a pack of 20 A4-size clear plastic folders (or 'clear books') imported from Japan. The brand is Kokuyo, which is known for great stationery. These have a cute 'Nobita' design (a character from the popular anime Doraemon) and are a light blue color. They feature a 'wave cut' on the top edge, which is basically a decorative scalloped or wavy cut instead of a straight edge, making them look a bit more fun and stylish. They're perfect for organizing and protecting documents, school papers, drawings, or presentations. You can see what's inside without opening them. A pack of 20 is great for students, teachers, or office use – you'll always have one on hand. They're a simple, functional, and charming piece of Japanese stationery that adds a little personality to your paperwork.
