i think its cool. . . an original idea. . . though kinda odd. i wouldnt get one myself.
there are only so many shapes you can chose from. . . hearts, or half moons, whats next? stars, horse shoes, rainbows, pots of gold. . . sounds like a 12 year old girl's sketches on her notebook . . . or the line up for the next lucky charms shapes!
what is next, eye tattoos? i think cosmetic contacts sound cooler
