Tattoo Ink & Pigment Mixer Machine is the perfect tool for blending tattoo or permanent makeup ink. The hand held mixer blends your solid colors, as well as helps create custom colors from two or more shades of ink. The Battery Operated Ink Mixer uses disposable sticks that easily fit on and off. The Mixer requires the disposable sticks and a AA battery, either not included. Make sure to mix your inks thoroughly before beginning your tattoo & permanent makeup.
