Thank you for viewing! This is a key case with a hook that can be easily attached to the shoulder strap of a school bag (randoseru). Prevents loss of keys. You can open and close the keys while still wearing the school bag without taking it off. It comes with a Velcro strap so it won't dangle. The reel key holder extends about 60cm. (Reel color cannot be selected) Made of laminated fabric, so if it gets wet from rain, wipe it off with a dry cloth. ★Size★ Length: Approximately 10.5cm Width: Approximately 6cm Depth: Approximately 2cm ※Photos ④-⑥ are reference photos. It is also popular as a gift for entrance to school or promotion. It's a popular item at events! Also, even after graduating from school, it can continue to be used as a key case for backpacks and bags. We have received feedback that not only children but also adults use it as a daily key case. We made it with care, but please refrain from purchasing if you are looking for perfection like a mass-produced product due to slight distortions. For those who understand handmade products, thank you very much m(_ _)m
