SB-16 (small batch) is a pink crelly with berry holo microglitters & matte pink hex glitters.
SB polishes are small batch mixes with limited quantities. Once SB-16 sells out, it will not return to the shop.
Opaque in 2-3 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.
