This is one of the best rolls of sandpaper I’ve purchased. Doesn’t get clogged up like the cheap stuff available and stays sharp for ages making it better value in the long run. Essential when rubbing down jointing compound on walls and ceilings. One strip of this on a pole sander did all 4 walls and the ceiling of a kitchen I’ve been working on. Only loses one star as Screwfix could be a little lower on price.
