SB-10’s Cousin is a more muted, pastel sunny yellow creme than the OG SB-10.
Opaque in 2-3 coats, depending on application. It also stamps & water marbles beautifully. Swatch wheel shows two coats with glossy topper.
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.
