Frequently Asked Questions
What types of tattoo work are these Mast Pro RM 0.30mm needles suitable for?
Mast Tattoo Pro Round Magnum (RM) 0.30mm needles are ideal for smooth fills, consistent shading, and work requiring good coverage without excessive skin irritation. They perform very well in artistic tattooing, body art, and permanent makeup, thanks to their stable ink flow and even pigment distribution. If you're looking for a balance between speed and a clean finish, this type of cartridge fits your workflow perfectly.
What is the difference between Round Magnum (RM) needles and other types of magnum needles or shaders?
Round Magnum (RM) needles have a more compact and rounded arrangement, allowing for more controlled penetration and more even ink dispersion. Compared to traditional magnums, they offer greater precision in medium-sized areas and reduce the sensation of "tearing" the skin. In relation to round shaders, RM needles cover more area with fewer passes, maintaining smoothness and stability, which makes a difference in long sessions.
Are these needles compatible with any cartridge tattoo machine?
Yes. Mast Pro RM needles are compatible with most rotary pens and cartridge system tattoo machines available on the market. The fit is secure and stable, preventing unwanted play or vibrations. Still, as any experienced professional knows, it's always good practice to confirm that your machine follows the universal cartridge standard.
Is a 0.30mm diameter suitable for beginner tattoo artists or only for professionals?
The 0.30mm diameter is an excellent choice for both beginners and experienced tattoo artists. For those learning, it offers more control and margin for error, helping to avoid excessive trauma to the skin. For professionals, it guarantees versatility and consistency across different styles and techniques. It's that "safe size" that works well for most jobs without compromising the final result.
