Mast Tattoo Pro2 Needles Cartridges #12 Round Shader 50 Count - Smooth

In this review the Mast Pro2 #12 Round Shader 50 count cartridge pack is examined for tattoo artists who want consistent, disposable cartridges that balance precision and reliability. The reviewer found these cartridges best suited to practitioners focused on smooth shading and controlled ink flow; the single biggest reason to buy is the upgraded pro pins and stabilizing cartridge system that deliver steady performance across multiple sizes. Overall this review highlights practical performance, build details, and the one limitation buyers noted about ink retention.

Key Features

• Upgraded pro pins: The refined needle pins provide smoother tattooing and more consistent drag for shading work.
• Precision cartridge system: A stabilizing design keeps needles steady for accurate lines and consistent shader passes.
• Full membrane protection: The sealed membrane guards against ink backflow, helping maintain hygiene during sessions.
• Mixed round liner sizes: The included 3RS, 5RS, 7RS, 9RS, 11RS sizes in one pack cover a wide range of shader and liner needs for versatile use.
• Disposable construction: High-quality disposable materials reduce cross-contamination risk and speed up workflow between clients.
• Compatibility: Works with any cartridge system grip, simplifying integration into an existing kit.

Who It's For

These Pro2 cartridges suit professional tattoo artists and advanced apprentices who do frequent shading sessions and need a mix of round liner sizes in a single pack. The balanced needle feel and stable cartridge seating help artists who work on portraits, soft shading, or textured fills where smooth ink delivery matters.

Less experienced hobbyists or artists who prefer single-size bulk packs for heavy liner-only work might look elsewhere, since this mixed 50-count pack focuses on round shader/liner versatility rather than concentrated specialty magnums or curved magnums.

Pros & Cons
