This is an Otaiko stop clip, used to prevent the Otaiko (drum) knot and obi tie from slipping or loosening. The corners of the clip are rounded, so they won't damage the obi and can be easily clipped on. Obi made of synthetic materials like polyester tend to be slippery and difficult to tie, but this clip will hold them firmly in place. It can also be used for knots like Kai no Kuchi and Kichiya Musubi, which tend to loosen without an obijime (obi cord). It's also recommended for men who find their obi tends to loosen. Since it simply fixes the obi without tying, it's convenient for those who have shoulder or arm pain and find it difficult to tie the obi in the back, or for those whose obi is short and find it difficult to create an Otaiko knot. Using it on the left and right edges of the Otaiko, in the part hidden by the te-saki (hand tip), also helps prevent the shape from collapsing. There are many other ways to use it. This item greatly expands the range of convenience depending on how you tie and use it. Material: Stainless steel Size: Length 5.8cm x Width 1.3cm #OtaikoStop #KimonoDressing #AzumaStyle
