Was strolling in my local grocery and saw these displays. I only purchased 2 of the liquid liners, a matte black and a nano-glitter laden teal--both say they're waterproof. I let them dry on my hand just now and licked just once at them--obliterated. Now I suppose they'll be more waterproof in a fair test with waterdrops but geez. Anywho the lipstick looks and smells great! I think I'll exchange the liners for the lipsticks.
