What sets Neater Bags apart from the competition is that they dispense one at a time, like tissues — no more having to fumble around with a roll of bags to rip one free. The bags also have tie-handles for easy closing and carrying and are durable and leak-proof. Neater Bags come with their own dispenser that has a bungie zip cord on the back that will make it easy to attach to any leash or collar. Bag dimensions are 9" x 13".
