Lights Will Guide You has a dark fir green jelly base with green flakie shimmer (I think they're duochrome, in some angles the glitter flakies look purple) and copper hex glitter in three sizes. Application was a breeze, three thin coats plus one coat of Essence Better Than Gel Nails Top Sealer for perfection.
Cadillacquer polishes are available on Big Cartel, at Llarowe and at Harlow & Co.
I bought mine at the Big Cartel shop, of course, so the polishes could stay in the country insted of crossing the Atlantic twice... :-)
Lights Will Guide You was part of the 2013 Christmas collection, so sadly, it's no longer available. But Cadillacquer's creator Madeleine has since whipped up lots of other gorgeous polishes, so I'm sure you'll find something you like.
