RK Swiss made (non-leather) synthetic strap 18mm. Very durable. New old stock.

This is a new old stock Swiss made synthetic strap,and I've used some of these for over a year already and they still look good and are very durable. It's made of synthetic material, and it is not as stiff as plastic (ofcourse, it is not as soft as leather either), but it is very durable, and you can bend the strap, and even twist it to a coil, and it will just uncoil back into shape without showing any marks.  

This is a new old stock strap, and it is hard to find these straps already, so don't miss out on this one.  No more expenses on replacing leather straps every few months or so, as this straps last long. 

This is new old stock. Buckle shows some tarnishing.

The bottom of the strap where the buckle is inserted is 15mm wide.
