The case is made of Drum Dyed Hermann Oak Leather made here in the United States. The thickness is approximately 7 oz. The whole case is only one piece of leather with no stitching, but bound with heavy Copper Rivets. It comes conditioned with natural leather conditioner made of beeswax and other oils. It is recommended that you apply leather oil or conditioner periodically to keep the case soft and water resistant. The leather may vary slightly in color and how much it stretches. Your leatherman may fit snug right at first, but will wear in to fit comfortably. Made to fit Leatherman Supertool 300. Inside Dimensions: 4 1/2″ x 1 3/8″ x 3/4 For belts up to 1 3/4″ width. Handmade In The U.S.A. If you would like a custom case made to a different size or color, check out our store or contact me and I will be happy to try it for you!
