Dragonhawk Mast Pro Needle Cartridges - Round Shader

Dragonhawk Mast Pro Round Shader – needle cartridges for PMU and tattooing

Dragonhawk Mast Pro Round Shader cartridges provide you with reliable performance session after session. Each cartridge is EO-sterilized, single-use packaged, and tested for precision – whether you are working with PMU, permanent makeup, or artistic tattooing. The transparent plastic body and built-in membrane system reduce ink and pigment leakage, keeping your workspace clean and providing better control throughout the procedure.

Round Shader – what is it suitable for?

The Round Shader geometry gathers the needles in a circular group and is suitable for:

• Shading and filling brows in PMU
• Areola pigmentation and scalp pigmentation
• Soft transitions in artistic tattooing
• Combination techniques where lining and shading occur in the same session

A tighter Round Shader (e.g., RS7–RS9) provides faster coverage, while sparser variants (RS3–RS5) are suitable for finer detail work and contour shading.

The membrane system – why it matters

The built-in membrane in the cartridge acts as a check valve: it keeps pigment or ink in the front part of the cartridge and prevents liquid from being drawn back into the pen. The result is a smoother pigment flow, longer lifespan for your machine, and a cleaner work environment – especially important in PMU where precise dosage affects the final result.

Professional hygiene and safety

Each cartridge is delivered individually sealed and is intended for single use. Never open the packaging until immediately before the procedure. The cartridge must be disposed of immediately after the session concludes according to current guidelines for sharp, single-use materials. Store in a dry place at room temperature, protected from direct sunlight.

Compatibility and system information

Mast Pro Round Shader cartridges fit Dragonhawk’s own Mast Pro pens and are constructed with the industry-standard 3.5 mm grip. Most professional rotary pens from leading brands accept the same cartridge standard – check your pen’s specifications before ordering if you are unsure.
