A convenient holder for the Earth Rated refill rolls, it also includes 15 bags. This dispenser fits all standard-sized rolls and has an adjustable strap that allows it to attach to any size leash. The screw-on top keeps bags secured (not dropped or lost!) and the unique hook on the back of the dispenser is a great feature that holds the used bag for hands-free bag transport. Earth Rated products are the industry leader in terms of quality and most of all, affordability. At Earth Rated, we don't leave out the littlest of details - even our rolls’ cores and packaging are made from recycled content!
