Finally! I don't want to touch the inside handle of the door of a public restroom. Normally I'll grab it with some paper towel. But this is a good solution, especially for those restrooms that have hot air blowers instead of paper towel dispensers. The Toepender is a handle that attaches to the bottom of a door. Grab it with your foot.

A new restaurant near me has a handle that looks like a branch or something. The idea there is you put your forearm in it to open the door.
