This is an Otaiko-dome clip, used to prevent the Otaiko (drum) knot and obi tie from shifting or loosening. The corners of the clip are rounded to prevent damage to the obi, allowing it to be easily clipped. 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). Recommended for men who find their obi tends to loosen as well. Since it simply secures 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 with short obi where forming an Otaiko is challenging. Using it on the left and right edges of the Otaiko, in the part hidden by the tesaki (hand tip), also helps prevent the shape from collapsing. There are various other ways to use it. This item greatly expands the range of convenience depending on the tying method and usage. Material: Stainless steel Size: Length 5.8cm x Width 1.3cm #OtaikoDome #Kitsuke (dressing) #AzumaSugata
