It’s called the Urban Pets Hands Free Dog Poop Bag Holder Waste Knot. It’s a clip that you attach to the handle of the leash, with hooks from which you can hang a full dog-poop bag, after you’ve picked up after the dog. So now you don’t have to carry the full bag in your hand when walking. Easily holds two bags – will probably hold three if the dog is being extra-productive that day, although I haven’t tried.

This is, like, the best $6.50 thing I’ve ever bought.

It’s the little things, amirite?
