If you wish to purchase, please leave a comment before proceeding with the purchase. I will then create a dedicated listing for you. The material is indigo-dyed selvedge denim fabric. As it is a material used for jeans, it will fade. The denim shown in the product description photos is no longer available, so I will be making it with selvedge denim of a different color. I have obtained strong black thread, so it will be sewn with black thread. I have also obtained white thread, so it can also be made with white thread. The base length of the obi is S-100cm, M-110cm, L-120cm, and the width is 7cm. A width of 8cm is also available. When using 30cm of soft velcro and 10cm of hard velcro, the obi size can be adjusted to approximately 86-106cm for L size, 66-85cm for S size, and 76-98cm for M size. It is best to confirm your size by wearing a kendo gi and tightening it with the string. LL size can also be made. The width and length of the obi can be adjusted. If you wish to purchase, please contact me with your size and other details in the comments, and I will create a dedicated listing for you. There is no description of the item.
