Professional Carpenter here - this is a waste of money. Usually love fastcap but this is dumb. Eraser fell out after half an hour in my bags, the pencil is ok but there is no discernable benefit of this over a traditional carpenter's pencil, plus it's round so you can't scribe with it. Three stars because it's an ok product but no more because it's pointless.
