YStudio Brass Core Case, Mottled Peacock Color, Custom YStudio

This is a custom-made brass core case from Wai Studio, customized in a mottled peacock color.
Since it is a brass焼き付け (yakitsuke - heat-treated/blued) finish, the paint will not wear off with daily use, but the color may deepen with high humidity or water.
