3M 5.5 in. L X 4.5 in. W X 0.1875 in. 60 Grit Medium Sanding Sponge

More than a century ago, 3M started as a small-scale mining venture in Northern Minnesota, then named Minnesota Mining and Manufacturing Company. Now a global powerhouse, our products improve the daily lives of people around the world. But our success and longevity were not apparent from the start. We tried. We failed. We tried something new. Repeat cycle. Innovation and perseverance drove our founders and it continues to drive 3Mers today.
