I used this to repair a book my child tore, but I still have a lot left, so I'm offering to cut and sell it to those who need it. This is Page Helper from Kibundo Co., Ltd., also used in libraries. It's a super-thin reinforced tape made of polyester film, so it's flexible even after repair. Width: 1.5cm x Length: 1m Additional 1m units are available for an extra (+100 yen). Please comment before purchasing. How about using it to repair or reinforce picture books and other books? It will be shipped via Yu-Packet Post Mini. Please refrain from price negotiations for this product.
