【Instant purchase OK!】 Thank you for viewing. Please read the profile. This is a handmade key case. It can be attached to a school backpack with a carabiner. Made with laminated fabric, it is resistant to dirt and rain, and easy to handle. Recommended for stylish elementary school children who have started carrying keys. I think it can be used by both boys and girls. A belt is attached to the back, so it can be fixed to the school backpack and won't dangle even when running. When you open the zipper, there is a reel-type key holder inside. The reel is 70 cm long. Attach the key to it, and then pull the key and extend the reel, so you can unlock the key without removing the key case from the school backpack. It has a gusset, so keys can be stored comfortably! ☆The color of the actual product may be slightly different from the photos, but please understand that this is due to amateur photography. ☆This is amateur measurement. Please understand that there may be some errors. 【Size】 Approximately 10 cm long x 5.5 cm wide x 2 cm gusset ☆The reel extends approximately 65 cm. ☆This is a handmade product. We are looking forward to your purchase if you understand. For入学, preparation... How about a gift for a celebration? For mothers who are planning to let their children carry keys...
