Review by Liz on 26 Jun 2019review stating Ok, but could be better
I got two colors of this, the lighter of which arrived with a broken tip. I've sharpened it down about 2 cm, but the end remains kind of crumbly, so this won't do when I need a sharp end. The formula seems very waterproof though, and did not wash off easily from my hand after testing, even with some hand soap.
TL;DR: the formula is very waterproof, but the pencil does not sharpen very well. Overall OK for the price though.
