This MBL leash is handmade using line made in America. Each dog leash has a leather tag stamped with the Marine Biological Laboratory name. The leash is spliced and whipped with hemp to withstand pulling and tugging. Fixed on the end is a solid brass lobster clasp designed to help keep your pup safe and secure. We provide each Dog Leash handle with a solid brass O-ring to hang dog walking accessories such as poop bags, keychains, or flashlights.
