If you're an admin pouch enthusiast like I am, you'll love the Snack Pack. It measures 4x8 with a velcro panel on the back to stick to the inside of your bags, and a unique semi-gusset design that holds its own shape and springs back to being puffed up regardless of how you smash it. Easy to open, easy to see inside of, and perfectly sized to carry anything you don't want to lose in the bottom of your bag, it's a killer design that you'll love to use.
