SB-26 (small batch) is a cobalt blue creme with blue/gold/pink/purple shifty shimmer & iridescent crystal flakies.
Opaque in 3-4 coats, depending on application.
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. I recommend Take Your Base protective base coat.
