In Japan it is uncommon to wash the obi martial arts belt. However many of our international customers like to wash their belts. We recommend hand washing (with hand soap) and hang drying in the shade. Please note that regular washing will accelerate the belt's aging process and might cause it to shrink further than estimated. It will still be functional and last for many years though.

⏲️ It takes 20-30 work days to custom make your new belt, but we also offer a rushed service (10 work days) for urgent orders. The whole process is handmade and we always have many orders waiting in line. We will send you a completion estimate a few days after the order is placed so you know when it will ship.
✅ Because these belts are made to order and unique, they cannot be returned or exchanged. So please make sure to double check all the details before completing your order. Once we start working on the belt, no changes will be accepted. All sales are final.
