Stingray functions just as incredible as it looks. The Stingray skin is amazingly durable and resists wear better than most any product we know. Approx. size: 3. x Not to be compared to cheaper quality versions. Ours are made with grade 1 top grain cowhide leather interior. Note our mature skins have much larger calcium deposits -- the white studs/natural markings -- are much larger and more unique than others.
