The Perfect Line SB Abrasive is a non-woven abrasive on a roll. There are two varieties available: SB Abrasive Very Fine (red, P320) and SB Abrasive Ultra Fine (grey, P600). The rolls measure 100 mm x 10 m (W x L) and are packed in a box. This keeps the roll dust-free in the workspace. This abrasive can be used both wet and dry to roughen various surfaces by hand. Because the Perfect Line SB Abrasive is made of flexible material, it follows the shape of the object to be treated.
