A shader is a tattoo machine built specifically for coloring or shading in a tattoo once it has been outlined. This machine holds larger needles and delivers more power to cover larger areas of skin while tattooing. The types of needles used in a shader are often called "mags."
The liner tattoo machine is used to make the outline of any tattoo. The needles used in a liner are smaller so that they can make sharp, precise lines. The types of needles used in a liner are often referred to as "rounds."
Tattoo machines can range in price from $150 to $700 or higher depending on the manufacturer, features, and whether the machines are "production" or "custom."
