Nicole by OPI and Kellogg's Special K Partner Up For A Cause, Free Nail Polish

Nostalgia alert! Remember sending proof of purchase codes from your favorite cereal to get a prize, or begging your parents to buy you a box so you can get the toy inside? Well, you'll find yourself doing the same thing when you hear about this next collaboration (except, now you're old enough to get your own cereal!).

Kellogg's Special K and Nicole by OPI have teamed up to create three custom nail polish shades that will only be accessible via purchase codes. The promotion will coincide with a campaign to encourage women to "show off their confidence with color." For the entire month of April, customers will have the opportunity to get their hands on Challenge Red-y (a creamy red), Pros & Confidence (a creamy turquoise) and Be Ama-Zing! (a creamy pink). Simply sign up for the Kellogg's Family Rewards program and enter the codes from specially marked boxes of Special K products and you will get these exclusive polishes! Three purchases of eligble Special K products will get you a bottle of Challenge Red-y, while eight purchase codes will get you all three shades! Did we mention they're free? This makes eating breakfast even more important than it already is.
