Leather Rocks Glass - Brown Water Leather Wrap Barware - Personalized, Handmade, Bourbon, Whiskey, Groomsman, Wedding, Man Gift. Leather is handcrafted and made to order. 12 oz. glass is included. Our leather wraps have a tight fit but will slide off the bottom in order to wash the glass. The purpose of the wrap is to soak up the condensation while also giving your drinking glass a touch of "class" that can't be found anywhere else.
