Nails inc say "This fabulous collection of vibrant mini polishes also includes a Caviar top coat and Soho Silk base coat. Soho Silk will help these amazing neons look even brighter while helping to add strength to the nails. Caviar top coat adds the perfect, professional finishing touch for super glossy nails."
There are 6 neon colours in the set, but note that the bottles are smaller than usual. This is cheap for decent nail polish and the blue is forecast to be popular for the summer.
