Gearheads 液態矽膠C形環 5入裝

I was worried they'd be too tight, but the liquid silicone has just the right amount of stretch for a comfortable fit. Stacking two of them gives a really solid, secure feeling without any pinching.

The stretch on these is seriously impressive for the price—I've been stacking two at a time and they hold firm without pinching. The liquid silicone feels warm to the touch almost immediately, which makes a big difference. Definitely going back for another pack when these wear out.

The material feels durable, but the "extra strong" claim is a bit misleading—I've had a couple that tore after just a few uses. They work fine for the price, though, and the pack of five gives you plenty to experiment with stacking.
