1975 KINOUCHI LIMITED EDITION STRAPS WITH HOOKS (2 pcs)

1975 KINOUCHI LIMITED EDITION STRAPS WITH HOOKS (2 pcs) There is one plastic hook on each strap. The straps look new I do not really know what they are for but I do see the brand on Poshmark. Each strap is seperate from one another. Each strap has one plastic hook. There is nothing other than the silver wording. Both straps are identical in length, size, but the wording is different from one another. Do you have a use for these?
