Super rare item from a stationery store that has been around since the Showa era. Believed to be a promotional item from Gakken. This is paper for making a kabuto (samurai helmet) for Children's Day fair. (See photos) ⚠️ Believed to be an old item. Some items are not in very good condition. Please understand this before purchasing. I believe this is something only those involved could obtain. If you are interested or collect vintage items, please purchase this.
