MAST TATTOO Mast Pro SMP 3 Round Liner Cartridges 0.3 mm — Pack of 20, Sterile Clear-Tip

MAST TATTOO Mast Pro SMP 3 Round Liner 0.3 mm cartridges are single-use, sterilized tattoo needles engineered for precise lining and SMP work, supplied in a pack of 20 for professional use.

These Mast Pro SMP cartridges combine a low-profile housing, a protective membrane and surgical-grade stainless steel needles to deliver consistent ink flow and stable needle movement. Designed for scalp micropigmentation, tight liners and detailed cosmetic work, the 3 Round Liner (1003RL) formation and 0.3 mm needle diameter balance punch and finesse for crisp, repeatable results. Each cartridge is EO gas sterilized, individually sealed, and compatible with most cartridge-style tattoo and permanent makeup pen machines.

How do these cartridges improve precision during lining and SMP?

The 3 Round Liner layout concentrates three tightly grouped needles to create clean, controlled strokes while retaining enough pigment capacity for even saturation. The clear-tip housing offers better visibility at the point of contact, helping you follow hair patterns or tight outlines. A protective membrane prevents backflow into the machine, keeping performance consistent over long sessions.

• 3-needle round configuration for tight, accurate lines
• 0.3 mm needle diameter for fine detail work
• transparent tip improves visual control while working
• membrane barrier reduces machine contamination and ink backflow

What safety and sterilization features are included?

Each Mast Pro SMP cartridge is manufactured from surgical stainless steel needles and is EO gas sterilized, meeting common industry sterilization standards for single-use disposables. The cartridges arrive individually packed to preserve sterility until the moment you open them, and the smooth, low-profile housing helps reduce tissue trauma. Avoid reusing cartridges—single-use reduces cross-contamination risk and simplifies compliance with hygiene protocols.

• 100% EO gas sterilized prior to packaging
• individually sealed cartridges to maintain sterility
• surgical stainless steel needles for durability and corrosion resistance
• smooth edges and low-profile housing to minimize tissue disruption

Will these cartridges fit my tattoo or permanent makeup pen?

Mast Pro SMP cartridges use a standard cartridge interface to match a wide range of cartridge-capable tattoo and PMU pen machines, including Mast-brand pens. Installation is plug-and-play: insert, click into place, and you’re ready to work. If your device accepts standard cartridge modules, these should connect securely and run reliably.

• standard cartridge connection compatible with most pen machines
• simple snap-on installation for fast cartridge changes
