Usually yes, we can add stripes to a used belt purchased from ChokeSports.com. But the following conditions are necessary...
1) We cannot add it to F-500 (satin) and F-1000 (silk), because we have to unsew the belt. As satin and silk are delicate, we cannot remake it again.
2) Belts with old and the grazing surfaces cannot be updated. Same reason as above.
3) The space needed for a stripe is 12-15mm.
If you are interested, please contact our support team and we'll send you further details.
