MAST TATTOO Mast Pro Bugpin Round Shader Cartridges 20-Pack 1007RS — Clear HD Body, Stable Tension

These Mast Pro Bugpin 1007RS cartridges are single-use round shader tattoo needles sold in a 20-piece pack, built with clear, high-density plastic bodies for consistent ink flow and reduced machine stress.

Designed for professional artists who need fine, reliable shader performance, the Mast Pro cartridges combine a tight bugpin grouping with a transparent housing so you can monitor ink and keep your pen running smoothly. The pack includes 20 disposable cartridges in the 1007RS configuration — a seven-needle round shader arranged in a fine bugpin pattern — suitable for shading, filling, and soft blending on a variety of skin types.

How do these cartridges improve machine performance?

Mast engineered the cartridge body and internal tension so the needles track steadily and the pen experiences less mechanical strain. That stability helps prolong the life of your rotary or pen-style machine and keeps stroke consistency from session to session.

• High-density clear plastic body for stable needle alignment
• Optimized tension reduces wobble and motor load
• Disposable design avoids cross-contamination and mechanical wear

What makes the 1007RS bugpin configuration useful for artists?

The 1007RS is a compact round shader grouping of seven bugpin needles that gives softer fills and smoother gradients than standard mags or larger shaders. It’s ideal when you want controlled shading with fine detail and less trauma to the skin.

• Seven-needle bugpin layout for delicate shading and soft transitions
• Suitable for small to medium areas without overworking the skin
• Works well with dilute inks and soft shading techniques

How does the clear body help during a session?

The transparent cartridge housing allows quick visual checks of ink draw, air pockets, and needle cleanliness between color changes, saving time and ensuring consistent results. It also makes rinsing and priming faster and more reliable.

• Easy visual monitoring of ink flow and air bubbles
• Simplifies cleaning and priming between color swaps
• Assists in confirming proper needle protrusion and function

Are these cartridges compatible with my tattoo pen?

Mast Pro cartridges use the standard snap-in connection common to most cartridge-ready rotary and coil pen systems, so they fit the majority of modern grips and machines. Always check your device’s compatibility list and follow manufacturer guidelines for secure attachment.

• Standard cartridge connection for most pen-style machines
• Single-use disposables reduce contamination risk
• Pack of 20 gives value for busy artists or appointments
