A brand new 20mm high quality silicon strap for the new MarineMaster!! Retro looks, no waved design for expanding, a steel tube that fortifies the push pin hole. Not always in stock! The strap is not as soft as the thick new Turtle strap, but softer than the new Willard straps. It tapers from 20mm between the lugs to 18mm at the buckle. The keeper is black.
