Purchased from Rakuten Ichiba, Hariti. Used 2-3 times! I was able to securely hold my child who tends to move around, so I could let them sit in the chair with peace of mind! They didn't seem to dislike it too much. Eventually, they were able to sit normally, so I stopped using it. I would like to pass it on to someone who can use it. Please refer to the images (borrowed from the official website) for the size, etc. Baby and Kids Chair Belt Color: Black Check Retail Price: 2,970 yen The color "Black Check" of this product seems to be an original from the shop Hariti.
