i'll admit that opi rainbow connection is a polish i should have passed on. but how can you pass up a nail polish called rainbow connection? the lovers, the dreamers, and me... i needed it in my life!
the difference: deborah lippmann happy birthday uses red and blue glitter while opi rainbow connection and sephora by opi spark-tacular! use magenta and aqua. spark-tacular! and happy birthday have two sizes of glitter (although spark-tacular! is much more fine), while rainbow connection has three.
top to bottom:
happy birthday. spark-tacular!. rainbow connection.
(all over zoya pandora)
my favorite (hands down) is
rainbow connection...SO happy that i picked it up.
