This bag is made of a supple black leather and is square shape. The size is 7" by 7" with a 2 inch wide gusset which makes the bag 2" thick. The flap is rounded with a brown suede leather sew around the outer edge and closes with a round button sew to the front of the bag and a button hole slit on the flap. On the back inside of the bag there is a smaller half moon pocket. The 1 1/4" shoulder strap is adjustable with a brass buckle that can be adjusted from 50" to 61" long. We make the bag so the buckle is in the back when wearing the bag.
