Index: M&S- Rainbow, reviewed this in an earlier post. Easy to apply even without special base coat.
Middle: Sally Hansen Nail Prisms - Diamond - particles very fine, polish quite sheer so you will need a zillion coats. I expected more punch from this polish. Doesn't dry fast or well, has weird rubbery squishy feel like it's not dried properly. Can easily leave a mark.
Ring: China Glaze - OMG - Pain to apply without base coat but very holographic
Little finger: GOSH - Holographic - Best of the bunch but need base coat for best application. Dries fast to give foil finish. Need I say more (unless you want me to).
Thumb: Milani - HD - Quite chunky particles, more inline with CG Kaleidoscope polishes. Dries with that rubbery squishy feel like SH.
