Welcome to part II of What A Pair, the second installment of my series on double-your-pleasure makeup products. First, we looked at lip liner and lip gloss duos and now come these awesome eyeliner and eye shadow duos. These are perfect for those of you who like to travel light. Not only are they functional and pocket sized, they are also great time-savers!

Duo Eyes ($22) is a cool invention for the gal on the go from Valerie Beverly Hills. One side of the wand houses a rich and creamy chocolate brown "smudgy" pencil eye liner and the other side houses a frosted gold cream shadow.

This new eye shadow formula has recently arrived from Italy. The color can be used wet or dry, it's oil-free and it won't crease.

Avon Shimmer Shadow & Liner Duo ($3.99) is a two-in-one eyeliner and eye shadow product available in five shades. It contains a silky liquid eyeliner and brush on one side, and a shimmery cream-to-powder eye shadow and applicator on the other side.

I haven't tried it, but the reviews claim that it doesn't fade, feather or crease and that it lasts for hours. At this price, I'd say it's worth a try!
