I picked up these lip stain markers at the Annabelle/Marcelle warehouse along with a couple of other products and so far they have yet to disappoint.
I picked up 3 shades, Marvelous, Punky Pink, and Melon Splash.
These can be wore alone (with a build-able coverage) or layered underneath a gloss. I get about 4-6 hours wear out of them when layered under a Stila lip gloss (depending on how heavy handed I am with the marker). They completely outshine the Covergirl lip stains (even at regular price).
The only down side is: I am not a fan of the felt tip marker like applicator. Maybe it's because I have yet to master the art of applying the lip stain, but I find sometimes I get a harsh outline of my lips if I'm not careful. When I use the Annabelle lip stain marker I feel like I'm 5 again and have to remember to stay within the lines.
According to their web site, these appear to have been limited editions, so chances are they are no longer available... Shucks.
