i'm intrigued...and i've been staring at it for the past 6 hours (leaving it on one of my smaller screens) and thinking about it the whole time.... i really want to try it, but don't want to spend a lot of money (the bottles are only 0.4oz).
I can't decide if I like it or not either. But, I don't usually like much fuss with my nails. Just a solid color, or glitter polish on the tips if I'm feeling crazy. I think Revlon makes magnetic nail polish. I know I've seen it at Target.
I think it sounds fascinating. I remember coming across this on a blog a while back. Apparently it was Chanel or something that first did it as an LE thing and people have been clamoring for it for quite a while so some other brands decided to fill in the supply.
W has a couple of these (and by "a couple" i mean "at least five and i don't want to know the exact number"), she thinks it's a neat idea but they're not really worth it. The duochrome ones are much more interesting and not as expensive.
