As leather is a natural product thickness obviously do vary but generaly medium is approx 0.80 - 1.00mm, thin is approx 0.3 - 0.40mm.
This leather is sold per square, each square equates to approximately 12” x 12” (305 mm x 305 mm). If you require 4 square then just order 4 in the quantity and we will pick a suitable skin or skins.
Please note leather is a natural animal product and as such, is not uniform and will contain natural flaws in the skin including sometimes pin holes etc and will vary in thickness. By purchasing from us you agree and understand this and accept that natural flaws and thickness variations are an inherent fact of purchasing natural leather and therefore is not a reason to return the skin for refund.
It is normal organ building practice to always order slightly more leather than you require so you can cut out or avoid such natural flaws that may occur within the skin. For further details please see our terms and conditions page and the relevant section on the purchase of leather. If you are at all unsure of what leather to purchase or the type required please contact us first for advice.
