Plastic Poop Bag Holder

OK, you don't have to use it for plastic poop bags.  It can be for plastic bags of any type, whatever you use them for.

Here's mine, hanging on the wall next to my front door.  So it's easy to grab a poop bag when I'm on the way out the door with my dog.

It works for holding mail, too.  In fact, that's originally what it was supposed to be.

You can get one here if you're interested.
