I spent the whole day (literally) trying to find rubber straps very similar to the one in the attached pictured (sorry for the poor quality). It's a 22m tapered to 20mm x 3.5mm thick all way through. I wonder if anybody has seen something similar somewhere? The most important features I'm looking for are the leather (or leather-like) insert stitched to the rubber AND a different leather color (preferably blue tones).
Any directions are very appreciated.
