Nails Inc and Colgate recently got together again, when you bought the toothpaste you got a free nail polish. The deal was going on in the UK in Boots. This time around there are three polish choices, this one - a vivid blue cream, a baby pink cream and a orange based red cream.
While this years polishes have the same names as last year the colours (red and blue) are different. I don't know about the pink one. You can see 2014's Optic Wave here.
