This stuff really fills in the ridges in your nails! I didn't think I had ridgey nails but the surface was so smooth once I painted this on. I got this as a door prize but I will definitely be buying this!

This dries super fast and keeps my nails from yellowing from my wearing dark polishes. A must-have for me. !.------------------------ 2007 UPDATE: If I want to pay what MK wants for this I'd rather buy high end brands or even MAC and Urban Decay.---------------------------------------------UPDATE: I used to love mk products but found out a lot of interesting information on pinktruth.com regarding the products and company. Turns out they are a bunch of scam artists after all. So sad.
