Is this kit enough to start tattooing?

It includes the pen machine, an Airfoil power supply, a box of WJX cartridges, a foot pedal and a case. You still need ink, practice skin and hygiene supplies.

Does the Mast pen work with other cartridge brands?

Yes. The machine is stated as compatible with all cartridge needle types, so standard cartridges from other brands should fit.

How heavy is the machine?

The pen weighs 120 g and is 11.7 cm long, which is light for a rotary pen and close to the weight of many comparable pen machines.

What motor does it use?

It uses a Japanese motor with a geared drive. Mast says this gives quiet, low-vibration running, though no stroke length is published.

Can I use the pen with a different power supply?

Yes. It is a standard rotary pen, so it can run from another compatible power supply with a clip cord or RCA connection, depending on the pen's connector.

Is it good for lining and shading?

It is a general-purpose rotary pen that takes standard cartridges, so it can do both. Check the stroke length before buying if you need a specific feel for either.
