PLEASE NOTE - SPLITS ARE MORE EXPENSIVE PER KG DUE TO THEM BEING THINNER - YOU GET A LOT MORE AREA / SQ FT FOR THE SAME WEIGHT AS THE 4.0MM THICK LEATHER These are off cuts of the leather we use for making our weightlifting belts. They are sold by the kilo. If you would like several kilos add the required amount to cart. They are various shapes and sizes, some long narrow pieces and some shorter squarer pieces. We can't select pieces for you unfortunately (we try and pick pieces which we think are useable for a wide range of applications), we will weigh an amount (and usually chuck in a little extra) for you and box it up and ship wherever in the world. We currently have various leathers you can choose from: Natural double butts. These are 3.5/4.0mm top grain natural coloured Italian vegetable tanned leather. These are used to make the core of our weightlifting belts. Black crust double butts. These are 3.5/4.0mm top grain black dyed through Italian vegetable tanned leather. These are used to make the core of our weightlifting belts. Black finished double butts. These are 3.5/4.0mm top grain black dyed through Italian vegetable tanned leather. These are used to make the top of some of our belts. They have a glossy / finished appearance. They're the same as the black crust but the top has been finished. Natural 2.5mm splits. These are 2.5mm vegetable tanned splits which are natural colour. These we use in the core of our weightlifting belts. They are firm / stiff even though they're splits. Black 2.5mm splits. These are 2.5mm vegetable tanned splits which are dyed black all the way through. These we use in the core of our weightlifting belts. They are firm / stiff even though they're splits.
