The navy formal bag is unused. The navy cloth bag with a pink heart-shaped bird embroidered on it and the GAP tote bag have been used quite a bit, but they are still sturdy. The navy backpack has detachable shoulder straps. You can also remove the shoulder straps and attach them to the included pouch. The Laura Ashley floral pouch and the brown checked bag have been used a few times. The red bag has "FILA" embroidered on it. It has two outside pockets and is made of nylon, so it's lightweight.
