We have a few artifacts made by TSL which uses this "TSL special" leather (including our favorite Pen Holder Clip). Their leather feels incredible in hands so naturally, I tend to pick it up pretty often when a notebook is wrapped in this cover. You can definitely see a lot of my personal imprints from natural usages like the darkened area where notebook cover folds in half, as well as some extra customization including wabi-sabi, embossed stamp and stenciled letter "w" on the back cover.
I hope you enjoy witnessing how the leather ages and wears in if you have one of their natural nude leather artifacts.
p.s you can see all of their leather covers in different sizes here!
