Prodyne BBQ Tablecloth Weights Set of 4 - Heavy Duty Outdoor Picnic Clamps for Windy Days, Patio Parties & Camping Trips

Maybe not their intended purpose, but I use these to keep my shower curtain liner from blowing in on me, while I am in the shower. They work wonderfully. They are a tad bit clunky, but not in an irritating/aggravating way. Going on just over a month in use and they show no signs of rusting.UPDATE (13 March 2021): Two have little rust spots (as you can see very minor on the clips) and they are a little dull due to the hard water in my area, but they are still working wonderfully keeping my shower curtain liner weighed down. Still lovely, still love them, and still would recommend their purchase.UPDATE (12 October 2023): I, periodically, soak them in CLR to get rid of the water deposit buildup and they still work, perfectly, as shower curtain weights (new picture added).
