This is one of the new Rapido polishes that have been out for Spring. It is a grayish blue like Eyeko – Rain, so I’ll compare them for ya!
Borghese – Castello Blue (index and middle) compared to Eyeko – Rain (ring and pinky)
I prefer Rain because it has a more opaque base and kind of pops a little more.
I thought since it was a Rapido polish, it would be opaque and thick, but its actually a really glossy and not so thick polish.
