I don't know what it is but lately I've been obsessed with
mark.'s Mini Mark It Stick for Eyes in the color Shell.
#1 Its only $6.50
#2 Its one of mark.'s Hook Up Products so I always have it "hooked up" to whatever lipgloss I'm wearing that day & throw it in my purse for touch-ups
#2 Its the perfect pearly color with just the right amount of shimmer
#3 The ways you can use it are endless ~ as a highlighter (under brows, inner corners of eyes, cheekbones), as actually eyeshadow, as eyeliner (my favorite to use on my waterline, it instantly opens up your eyes) & even over lipstick for a little extra shimmer!
Obviously perfect for traveling ~ you know this is one of the many beauty products I brought with me on vacation!
