Review on Multi-Purpose Set of 20 Colorful Silicone Ties: Bag Clips, Cable Straps, Bread Ties, Rubber Twist Ties, and More! by Matt Welch

I've only used 3 out of 20 so far but I like them really. They hold tension very well when the "tail" with the protruding rings is pulled through the small hole in the "head". It takes a little force to pull the tail out, and the larger the diameter of the rings, the longer it takes, but they will stretch and stay in place. At first I thought the tail might break because it stretched so much when pulled through the hole, but it doesn't break even when pulled hard, and doesn't stretch or lose its shape at all. It's a neat little invention. . . .
