Types of acrylic paint for nail art?

[Hart&Nails]

I heard you can use acrylic paint from craft stores. I have a few and they seem to work really good. Is there a certain type that I should use that can work with both acrylic and gel? I am also looking for detailing brushes super thin to get really small nail art. Ive got some from ebay and craft stores but I don't know any that are good.

Sam Biddle is a good place to look at.
