I got these polishes about a year ago and reviewed the one called "Cherry Liqueur". I swear I've worn "Horizon" as well but I'll be damned if I can find it on my blog!
"Cobalt" is a fine shimmer, lit-from-within, glowy dark blue. It's very smooth to apply and dry quickly. This is 2 coats over Sally Hansen Nail Quencher and MegaShine top coat. I think that these are not 3-free, it has a familiar old whiff to it :)
I think these are now discontinued, they were being sold incredibly cheaply on eBay for a while and I think some might still be there. I love these polishes, I think I might be cruising eBay a bit later to find other colours... But first, I must make a cream cake!
