Needed a dog poop holder with a bigger hole to connect to my existing dog poop roll. Also large enough to fit a carabiner. To use, tie a knot in your poop bag and put the knot into the larger hole and pull it down through the slot. Large enough to hold several poops before emptying!
NOTE: The above picture is it printed at 60%. I have included 55, 60 and 65% sizes, but I do find the 60% one to work best for me.
