Caviar Nails

Looks like even nail polish is coming out in 3D these days. I just came across UK brand 'Ciate' who have released these Caviar nail kits; made to look like caviar or mini cachou balls (for cake decorating). This nail trend looks like a lot of fun but a lot of maintenance. The texture looks really cool and the tiny little pearls make the overall look seem chic and polished. I'm wondering if these are acrylics though? 
I'd want to go to spotlight and try and find some tiny beads that could get me the same look.
