SB-7 (small batch) is an amethyst jelly with red microflakies, silver holo microflakies & iridescent unicorn flakies.
Opaque in 2-4 coats, depending on application. My nail macros show two coats.
I use high-quality & highly saturated pigments in my products, so staining is possible. It’s always advisable to apply a worthy base coat, especially under darker colored polishes.
