Good stuff
These have been around for a long time. They work great.

A vast improvment to steel wool.
I use these in my painting business. Awesome for sanding irregular surfaces. Nice for final sanding before finish coat. But the maroon color. The gray is too fine for most of my work.

Kinda pricy but you get a lot
We use this as a super light sand paper for acrylic and it does great. We have never had any problems out of it. If you sand with the same spot for to long it will thin out in the spot and your hand will be visiable through the sheet. Seems to last a while though.
