MICRO-MESH is a unique cushioned abrasive that produces a very fine and uniform scratch pattern. The mixed pack of 150 x 75mm abrasives is supplied in nine grades ranging from 1,500 to 12,000. The 1,500 is similar in grit range to conventional 400 grit wet/dry sandpaper. The 12,000 will leave a scratch pattern that cannot be detected by the human eye. MICRO-MESH offers outstanding results for a huge range of applications, and is proving to be extremely popular with pen turners, musical instrument makers, furniture restorers and anyone who requires a highly polished surface. This product is very hard wearing and can be washed and used over and over again. You will wonder how you managed without it.
