I bought quite a lot of various leather recently to do my own strap, but I will sell.few of them to fund the raw materials.
So here is the first one. Not perfect but pretty good.
Calf leather in dark dark brown, white full stitching.
20/18
Long : 11cm
Short : 8 cm
Thickness : 2.5mm
Brsnd new, freshly done.

Price is 35 euros including shipment en PayPal.
You pay only when you receive it and happy with it.
I am based in Paris but I can ship in EU. Sorry for other countries but too many strap lost in the past.
Thanks OF for the space
