Facebook: so I'm always giving product suggestions and reviews in Facebook...well--I'm now doing a favorite of 2011 series!!! Today I talk about Avon mega impact gel/pencil liner and urban decay 24/7. A huge advantage of the UD is the variety of colors! They last a long time :(even on the water line) but they are expensive. Avons liners are just as good but you can get them for around $3 and that's awesome!!! A major draw back is there are only 4 colors :( but they are gorgeous liners!!!
