Hi Sallyd615

Thank you very much for the questions and our apologize on the delay in answering.

These work in a very simple manner using the outside edge of your bathtub and gravity.

First, so you know, they come in a pack of three, one for each end and one for the middle of the shower liner. Now let's get started on the three easy steps;

1. You attach them, roughly 12 inches from the bottom of your shower liner. With one on each end of the liner (again roughly 12 inches) and then one in the very middle.

2. Adjust to being just above your bathtub edge but high enough so it's behind your shower curtain, if you have a double curtain setup.

3. Hang the weighted ends on the outside of the bathtub. Your Done!

Clingless Curtain Keeper will pull the shower liner toward the outside edge of your bathtub, solving the shower liner from billowing inward, adds back ~25% more showering space and helps reduce the water splashing out.

If you are curious about how the units attach to the shower liner, it has a backing and the front each have powerful magnets in them, which snaps it into place (see attached image). However, this does NOT require a metal or metallic bathtub. Additionally, this does not damage your liner and allow you to use on your next liner or take them with you while you travel!

Thanks again for the great question!

All the best,
