I purchased this but it's unused. There are scratches on the surface (see image 2). Thickness is approximately 1.5 to 2 mm. Embossing is applied to oil-tanned leather. There are irregularities in the embossing, wrinkles, scratches, stains, and color unevenness. Therefore, I have selected "Slightly dirty" for the listing. m(__)m The flesh side has not been sealed, so there is some fuzz. How about using it for leathercraft practice?
