INKin 27RM Curved Magnum Tattoo Cartridges, Finger Ledge, 16Pcs, #10 Bugpin for Rotary Pen

Designed for control, precision, and comfort

The INKin 27RM curved Magnum tattoo cartridges pair an ergonomic finger ledge with a curved magnum needle arrangement, offering a smoother handling experience and steady lines during shading. Crafted for professional use, these cartridges emphasize comfort and reliability without compromising ink performance, making them a practical addition to a rotary tattoo setup.

Key features and benefits of this cartridge line include a safety membrane that helps minimize ink backflow and stabilizes the needle during operation. The transparent tip body not only adds a modern look but also lets you watch ink flow and make timely adjustments as you work, enhancing control over delicate details.

The silicone wrap around the needles creates a secure lock and a soft touch, while a dedicated finger ledge gives you a resting point to reduce hand fatigue during longer sessions. The overall construction aims for a high-quality feel that tattoo artists can rely on as part of their daily workflow.

Each box includes 16 pieces, delivering consistency for sessions that require dependable performance. The 27RM curved Magnum tip is well-suited for shading and broader coverage while maintaining crisp edges. Although not a promise of results, many artists appreciate how this setup can support a smooth workflow, especially when switching between line work and shading in a single session.
