Rainbow Connection is one of my favorite polishes by OPI. I wear it all the time because it's quick to dry since it's just clear polish with pieces of glitter. I get lots of compliments because it's sparkly. The downside, it's no longer offered anymore. You can find some on fleabay, but they are ridic in price for a bottle of nail polish.
I just so happen to LOVE those Ulta coupons you get in the mail. I went in for blotting paper, and you can't just leave with buying one thing...and, since I always have a coupon, why not? Ha! I saw this and was like this looks just like my Rainbow Connection.
Figured I'd buy it as a back up when the other runs out or alternate between the two since it was pretty close. I kid you not, they are the EXACT same. So, ladies you can still get your rainbow connection if you wish:) It's the Kardashian Kolor Spring line by Nicole. The color is called Rainbow in the S-kylie.
