SB-11 (small batch) is a topper that is loaded with purple shifty shimmer & silver holo microflakies.
SB polishes are small batch mixes with limited quantities.
I've shown it here over On the Black, Lilacuña & Release the Kimbrel.
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.
