A key case with a reel that allows you to easily take out your key without opening your school bag. ■Material / Front: Laminate 　　　　　　Back: Cotton *Do not wash ■Size / Approximately 13cm long, 17cm wide (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 your 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 and replace it with a hook-type or snap-hook-type reel. *The reel may be a different shape from the one in the image. We make each one with care, but as it is handmade by an amateur, there may be some slight imperfections. Color...Black
