Review on 3M Drywall Sanding Sponge Medium by Kyle Kriglstein

This worked well to fix two large holes in my wall. I used a large amount of putty to cover the two holes and used this sponge to sand down the dried putty. From all that was said and done, nothing could be said to have happened to the wall. This is a good inexpensive product for small repairs and for those who don't want to invest in an electric grinder.
