Our leather belts are made from 8/9oz and are fully lined with 3/4 oz on the inside. We then add a heavy duty roller buckle that will last with the belt. Our buckles are stitched on vs the snap style. This will ensure the buckle never comes undone. We also line the belt keeper, because every detail matters. After all the dying, oiling, and buffing, we do a full submersion on sealer to penetrate every hole. Stitching Color- Brown Black White Red Orange Pink PM me for more info.
