Mia ★★★★★ Oct 22, 2026

I’ve used these on my sanding blocks for woodturning projects, and the 50-sheet pack lasts well since the adhesive really holds tight. The 2 3/4" x 16 1/2" size is perfect for my longer boards, cutting down on waste. Nice consistent grit that doesn't clog too quickly.

These sheets stay put on my file boards even when I'm really bearing down on a rough edge. The pack of 50 should last me through a few projects, which is nice.

The 50-pack is a solid deal for the price, and the 2 3/4" x 16 1/2" size fits my sanding block perfectly without needing to trim much. The PSA backing grabs hold right away, so no slipping mid-stroke, which is exactly what I wanted for finishing a batch of drawer slides.
