This dispenser is a convenient holder for our Earth Rated bags and also fits all standard-sized rolls. The adjustable strap allows it to attach to any size leash, while the screw-on dispenser top keeps bags secured (not dropped or lost!). Our unique hook on the back of the dispenser is a great feature that holds the used bag for hands-free bag transport. Includes one (1) unscented starter roll of 15 bags.
