Made of durable PVC, the see-through bag allows you to place personal item in a fashionable accessory when going to sporting events, concerts, or any outing where your carry-on will be checked. But don't let a security checkpoint be your only reason to have this great bag. Use it for work, school, the gym, or any where you are on the go.
