Matrix Color

3oz Matrix ColorInsider developer either 10vol, 20vol, or 30vol strengths. All devolver no matter what brand are stored in opaque bottles so that light doesn't pass through it because a chemical reaction happens when light passes through it for too long, it produces water....  So all 3oz developers I sell are packaged in black opaque containers to prevent its reaction with light so that it doesn’t make water.
