The Round Liner Needle Cartridges from MEga® come in both #10 and #12 needle gauges/diameters, offering versatility to cater to a wide range of artistic requirements. A notable feature of these cartridges is the integrated membrane, designed to enhance safety by preventing ink backflow. These cartridges are also compatible with all standard machines and grips. The round liners are designed to provide precision in line work, making them suitable for detailed designs and fine outlines. The presence of the protective membrane not only safeguards the artist and client but also ensures the integrity of the ink flow, allowing for crisp, clean lines. Whether using the finer #10 gauge for intricate detail or the slightly thicker #12 for bold outlines, these cartridges provide the artist with tools that enhance their capability to execute complex tattoos.
