A seemingly cute, large ribbon key holder! ♡ But actually, it's a reel-type key case! It doesn't look like a key case at all, so you can safely let elementary school students carry their keys (>◡<) I think it can be used not only by elementary school students, but also by junior high school students, high school students... and adults (o^^o) Because it's reel-type, you can stretch it out and unlock the door while it's still attached to the backpack! The ribbon fabric uses polyester quilting fabric, so it repels a little rain, and you can just wipe it off! Recommended for small gifts too♪ Size Ribbon: Approximately 16cm (length including key holder) x 15cm (width when the ribbon tails are spread out) Reel: Maximum length 40cm
