Ruby ★★★★★

The flexible cushioning layer really does the job on curved panels—my sander glides over contours without leaving flat spots. Cut them to fit my 3" × 4" pad in seconds.

Elizabeth ★★★★★

I’ve been using these interface strips on a curved car panel and the flexible cushioning genuinely makes the sander glide over the contours instead of digging in at the edges. They fit my 3" × 4" backing pad perfectly and hold up through several jobs, so I’m grabbing another pack for sure.

Eva ★★★★★

The cushioning layer really helps the paper follow contours without digging in, especially on rounded door edges. I've gone through a full set of these and they hold up well, no tearing at the grooves.
