these are 9" tall mini backpacks with adjustable straps and strawberry zipper pulls! I have tested them for durability by putting a weight in them and letting them hang for over 24 hours and they have performed wonderfully! I also wore it around for several hours and it held up well! The outer material is water resistant and there is padding around the outside of the bag. inside the main pocket there is an additional smaller pocket, and on the outside there are two side compartments and a main front compartment!
