RHEIN Gun Kit Wireless Pen Machine with 2 Batteries - Complete Tattoo

In this review the RHEIN Gun Kit Wireless Pen Machine is evaluated as a complete starter option for new tattoo artists and casual pros who need a portable, all-in-one setup. The biggest reason to consider it is the kit format: a cordless RNP28 pen machine with two 1500 mAh batteries plus a 14-color ink set and sterilized needles gives a technician nearly everything needed to begin practicing or doing small client work. The review focuses on build, battery approach, and whether the kit suits beginners or more experienced artists looking for a backup device.

Key Features

• Complete starter kit: The package includes the RNP28 pen machine, RCA cord, two batteries, charging cable, 14-color ink set and disposable cups so users can begin work without buying many extras.
• Cordless pen machine: The RNP28 operates wirelessly with two LED batteries for uninterrupted work and adjustable 5-12V output to handle lining and shading tasks.
• Compact dimensions: At 122mm by 28mm and 158g, the machine is light and easy to handle for longer sessions and detailed work.
• Sterile needles: The kit supplies 20 EO gas sterilized cartridge needles with 316 medical grade stainless steel tips for hygienic single-use application.
• Accessory set: Included grip cover tape, rubber gloves and a 30-piece cup assortment reduce initial setup time and support safe workflow.
• Compatibility: The RNP28 accepts all standard cartridge needles, allowing artists to swap preferred needle styles as needed.

Who It's For

The kit is best for beginners and apprentice artists who want a ready-to-use wireless pen machine and a full complement of inks, needles and disposable supplies. It is also a good choice for experienced artists who need an affordable backup wireless device for travel or practice.

Artists who require high-end, specialized pro equipment or who demand long, continuous sessions on heavy work may want to consider higher-capacity professional systems; some customers reported mixed experiences with battery life, so heavy-duty users should verify runtime against their session lengths.
