Cut to length black leather bellows strap replacement kit for single hole strap fixing.   Total length 300mm between stud centres.  Cut to length to make a pair to replace any length of bellows straps up to 140mm, length measured between centres of the press stud and the fixing hole. With chrome fittings.

You will need you own tools to cut the straps to length and to punch a hole in the leather for the fixing bolt.  Once the strap is fitted I recommend a drop of superglue on the fixing bolt/nut thread to reduce the chance of the nut working loose.
