VERY SOFT, VERY DUABLE, VERY RARE, IT WILL LAST YOU A LIFE TIME. They are about 0.825" thick. Fits large dogs and up. Handmade brown leather braided WITH METAL WIRE INFUSED. Leash is 3 ft long, been using it in the past few months, still in a GREAT condition. Collar has never been used since my dog never grew into that size.. It is a martingale style collar so it surely prevents from pulling. :)
