3M 3M917Na Hand Sanding Sponge Thin Fine, Grey

Good quality. Really pricey though, hope it reduces significantly in the future

Very helpful

Not much to say except this is exactly what I was expecting. The item can sand directly, but I intend to also use it as a sponge wrapped in my choice of sandpaper. Doing it this way allows me to hand sand and not leave waves because of the odd pressure from my fingers.

Works great.

I used this in the process of restoring on older sewing machine. It worked fine for what I needed. The only reason I didn't give it 5 stars is because I haven't tried similar products and have nothing to compare it to.
