Drop Pen is a new tattoo machine created by Equalizer for the comfortable work of every tattoo artist - from beginner to professional. At first glance, you can't even tell what a huge force she carries in herself. After all, its length is only 9 cm, and its width is 3.5 cm. But when you start working with it, you immediately realize that it is a high-class tool. The machine is very ergonomic and very comfortable in your hand, so you can work with it for a long time, almost without feeling tired. It is fully compatible with all standard tattoo cartridges and allows you to work in any technique and style. The body of the machine is made of lightweight, but at the same time durable aluminum, under which the top-end Equalizer 6W engine is hidden. It provides a strong and hard impact of the needle with a stroke of 3.5 mm, effectively coping with both contours and shadows, as well as full shading. This motor is virtually silent, and vibration from its operation is minimized. The Drop Pen machine has a standard RCA connector, which allows you to connect it to any power supply via a conventional clipcord. Adjustable extension (click system): 0-5 mm.
