Review (1/5): Zero stars
I agree this deserves zero stars. What a rip off! Not waterproof at all. It's so soft that you can't even draw a line decent. The tip breaks off when you sharpen it because it's a gel texture. A lot wasted and the little I was able to use was ineffective to say the least. I tried it multiple times thinking it was user error but it is absolutely the worst product I've ever spent my money on. I will demand my money back!
