While it's true that DL polishes may be worth the investment, akin to Butter London, RBL and other high end polishes, this one isn't worth the money. Multi-colored glitter suspended in clear, there is a very cheap duplicate out there that no one really realizes is almost a dead ringer. The glitter from Milani's Jewel FX line called 'gems' is 99% the same thing, the only difference is Happy Birthday contains square glitter (the smaller glitter) and Gems is all hex glitter. You can BARELY tell the difference unless you take a close macro shot of them side by side. At least its comparable to the old formula before DL changed the coloration of Happy Birthday to a more pinkish tone. Seek out gems before you drop big bucks on this DL shade, buy the dupe and save your money for another DL polish that isn't easy to copy.
