三角形砂紙海綿 320 粒度，10 入

I was dreading hand-sanding the curved sections of my guitar project, but these sponges saved me. The peel-and-stick design made swapping grits quick and fuss-free, and they really do grip tightly to the tool.

Contoured edges on a chair rail had me fighting with regular paper, so these triangle sponges were a relief. The 320 grit cuts smooth and the peel-and-stick pad hasn't budged on my micro sander. Ten in a pack means I'm set for a while.

The peel-and-stick backing held firm through a whole drawer project without slipping once, and the 320 grit cut smooth enough that I barely needed a finishing pass afterward. My micro sander finally feels useful on curved edges now, which is exactly what I was hoping for.
