☆ Announcement ☆ The fabric used is commercially available. A carabiner can also be attached, making it compatible with backpacks! (Please prepare the carabiner yourself as it is not included.) A key case with a reel that allows you to easily take out your key without having to open your school bag. ■ Material / Front: Laminated 　　　　　　Back: Cotton *Not washable ■ Size / Approximately 13cm in length, approximately 17cm in width (when unfolded) Securely attach it to your school bag with a hook or Velcro, and you can easily take out your key by opening the zipper. A reel is built into the inside of the zipper (pocket part), making it convenient to pull out the key with a "shlurp". It's safe because the key is not exposed. It's a type that wraps around the shoulder strap of the school bag, so it won't dangle and get in the way. The reel key is designed to be replaceable if it breaks. Please purchase a hook-type or hook-and-loop type reel and replace it. *The reel may be a different shape from the one in the image. We are careful to make each one with care, but as it is handmade by an amateur, there may be some slight distortions.
