I am selling a very gently used (only a few times) 18mm size Nomos black shell cordovan strap, short length. This came off a new Tetra, but I needed the standard (medium) length. It should fit wrists up to 6.75", but more comfortably 6.5" and less. It is in excellent condition. Price is $55 shipped and paypaled within CONUS. Retail is $90 on these. Please PM with any questions. Thanks for looking!
