Full-Grain leather: Crazy Horse leather is a type of full-grain leather that has been treated with wax and oils to create a rugged, distressed appearance. This treatment also makes the leather more resistant to water, scratches, and other types of wear and tear. Crazy horse leather tends to have a softer feel than other types of leather and can develop a unique patina over time, giving it a vintage look. Super Convenient: This Black Leather Backpack is exceptionally convenient for use, as it has one large compartment for big items, extra pocket for flat things, like a tablet, laptop or folder, as well as an inner pocket for small stuff. The front pocket is perfect for little things that should always be on hand. Secret Pocket: A secret pocket is an important feature that will help you store peculiarly valuable things and documents. It is equipped with a zipper and placed at the very back of the backpack, so the access to it is impossible while you are wearing the backpack. Unisex: Thanks to its minimalist style, this Black Backpack will suit both men and women for everyday use, business trip or vacation. You will definitely get a lot of compliments from your friends. approximate dimensions are 16 and 1/2 in tall by 16 and 1/2 in across
