Butter London Disco Biscuit is a gorgeous neon Barbie pink, with blue sparkly dust in it. This colour is very pretty and girly.
Butter London Disco Biscuit is very sheer, this was four coats and I still had a slightly visible nail line plus one top coat of Seche Vite. It also dries extremely matt, so a top coat is a must if you want the colour to be glossy. Also by putting on a top coat you achieve a jelly look to your polish, which I prefer.
