Super high quality leather with alloy pyramid studs.  Hand crafted and made with love. 

See the below from APE Leather's site:

PLEASE MEASURE. The best way to figure your size is to measure a belt that you are currently wearing from the fold at the buckle to the hole you wear it on as shown in the diagram. The size of your pants and the overall length of the belt are irrelevant. It's good if the belt is the same width as this one which is 1 1/4".This is a high quality black leather belt with two rows of nickel plated pyramid studs. It has a removable buckle. It is 1 1/4"" wide and adjusts with 5 holes at 1" increments. Choose your size from the drop down at the right of the photo. The sizes shown are at the middle hole. Example a 34 would cover from 32 - 36". We use only real leather from hand picked hides, no bonded leather like that junk in the mall . This belt will last a long long time. All of my products are made by me in my own workshop. I use hand methods when called for and good machinery for the rest. I have been doing this for over 30 years and workmanship and quality are great.
