I was searching for a green, reusable bag that will allow me to carry it like a purse. I love to take walks in the fresh air, and sometimes I find myself walking to a Department store a little less than a mile away, so I needed a bag that was durable, spacey, and had shoulder straps. I found the perfect bag, The Drink Pouch Messenger Bag by TerraCycle ! This bag had it all, shoulder straps, durability, awesome space, and the best of all, its made from everyday recycled products!
