I purchased this for work and used it for about six months, but I'm selling it now because I no longer need it. It's a vertical tote, so when sitting on the train, I think it's the perfect size to place on your lap without extending into the space beside you. It has many pockets and is an easy-to-use tote bag. Outer material → Ballistic nylon Size → Approximately 35 cm tall, 33 cm wide, and 9 cm deep MADE IN USA Product Description This tote bag features an asymmetrical pocket on the front. The main opening can be secured with either a zipper or a snap button.
