Purchased at a.v.v for around 1200 yen. I bought this at the same time as the dress I have listed separately. The length can be adjusted by tying the strings (each string is about 40cm long). I bought this for my child, but it seems like it could be used by people of any age. For reference, I've included a photo of it paired with the dress. Please note that the dress is sold separately. I've only used it 2 or 3 times, but it's a used item that has been stored at home, so I would appreciate it if you could understand that.
