Yakyū, which means "baseball" in Japanese, is a bright cobalt blue creme.
Opaque in 1-3 coats, depending on application.
Swatches courtesy of Jennifer (the_polished_pineapple), Kiz (onehundredbrushes), Felicia (mypolishedtips13) & Christy (hospitalhands).
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.
