The type of leather is unknown, but it's a firm leather. I acquired it over a decade ago, but it's been stored with little use. Dimensions when the top of the bag is opened into a square: Width: Approximately 35cm Depth: Approximately 21cm Height (center): Approximately 24cm Base: 22 x 13cm While it has little wear and is generally in good condition, it is a used and old item, so it has some signs of use. Please refrain from purchasing if you are concerned about signs of use, damage, or dirt, as this is a used item.
