Astral Violet Epoxy Resin Guitar knobs

Inspired by deep-space hues and shifting nebula light, Astral Violet blends cosmic blues, smoky violets, and soft metallic undertones into a polished resin finish that feels alive under light. Each knob captures slow, celestial movement—never flat, never repeated.
