I'm really not sure why a polish as amazing as this one is not a part of their core line. Neither are many of their glorious glitters, like Atlantis, Electric Lilac, Gold Digger, Nova, and Shooting Stars but I've seen all those and more at supply stores! I bought MS at a supply store for a mere $2.50. The base is an inky dark navy blue jam packed with teal, copper, and royal blue glitters. LOVE!
