It's becoming more common for artists to use a rotary tattoo machine. This is much easier than the barbed coil machine because it requires less maintenance and technical know-how.
Rotary tattoo machines can make the tattoo experience much less painful. With no vibration or buzzing, clients perceive that they are experiencing little to no pain. For the artist, rotary tattoo machines are lightweight and easy on the hands, reducing common gripes like hand fatigue and finger cramps.
