The dog poop bag dispensers are made from high quality PP plastic. Its ergonomically designed shape makes handling, opening, and closing a walk in the park. We strongly recommend using these poop bags, which contain d2w for fast degradation, with this dispenser. Even if you decide to use other manufacturer's bag rolls, please be assured that this dispenser will fit. For an added convenience, our dispenser comes with one carabiner that will fit most handles and leashes.
