Hello,
I love doing watermarble manicures. They are little tricky but they come out absolutely gorgeous every time, all you need is right nail polishes. Back in 2015 Pipe Dream Polish (an indie polish brand) released a collection of neon polishes which went crazy popular among nail artists because they water marbles like dream. So after a lot of struggle i could order a set for myself and i was so happy to see the results. These are my favourite polishes for watermarble.
