Mast Ocean Heart Cartridge Needles (0.25mm Diameter, 5MM Taper | Box of 20)

The Mast Ocean Heart is not simply a needle cartridge — it is the world’s first multi-color gradient permanent makeup cartridge, and a landmark in PMU industry design. Achieved through advanced multi-color injection molding technology, each Ocean Heart cartridge carries a unique, enchanting color gradient that makes every single piece a visual work of art. No two cartridges are identical, and no other cartridge in the PMU industry looks or performs quite like this.

The 0.25mm diameter combined with a 5MM taper makes Ocean Heart particularly well-suited to fine, precision-focused PMU work — delivering the needle control needed for hairstroke brows, nano strokes, detailed lip blush lining, and eyeliner work where accuracy is everything. Beyond aesthetics, Ocean Heart inherits the signature coloring performance of the Mast Pro series and elevates it further — upgraded smooth inking, improved needle durability, and enhanced operational stability — giving artists a tool that is as capable as it is beautiful.

World’s First: Multi-Color Gradient Cartridge Design

Ocean Heart introduces a genuine first to the permanent makeup industry: a cartridge produced using multi-color injection technology to create vivid, dreamy gradient visual effects across the body of every cartridge. Each piece transitions fluidly between blue, violet, and rose tones, making every cartridge a distinct, unrepeatable aesthetic object.

This is not decorative coating or print — it is built into the structure of the cartridge through the manufacturing process itself, making the gradient permanent, consistent, and unique per piece. Every Ocean Heart cartridge is both a precision PMU tool and a collector-quality visual statement.

Ultra-Slim Long Taper for Precision Work

The next-generation cartridge taper design was developed through direct consultation with world-renowned embroidery artists, resulting in a thinner, longer, and ultra-slim taper profile that delivers measurable improvements in precision work:

• More accurate pigment implantation depth
• Enhanced visibility of the needle tip during delicate procedures
• Cleaner, more refined results with reduced margin for error
• Easier needle positioning for fine detail work

The 0.25mm diameter and ultra-slim 5MM taper design makes Ocean Heart particularly suited to:

• Brows — nano strokes, hairstroke techniques, and soft microshading
• Lips — soft shading, lip blush, and precise lip lining
• Eyeliner — fine line detailing and controlled shadow work

Smooth Ink Flow and Stable Performance

Ocean Heart cartridges are engineered for professional consistency throughout every session. The cartridge system delivers smooth, continuous ink flow, stable needle movement, and reduced operational vibration — resulting in better pigment retention, more even color distribution, and improved healing outcomes.

The Ocean Heart inherits the coloring performance foundation of the Mast Pro series, then upgrades smooth inking, needle durability, and operation stability to give artists complete freedom to perform their best work at every session.

Durable and Reliable Needle Structure

Built with high-quality materials and rigorous quality control, every Ocean Heart cartridge is engineered for long-lasting sharpness, strong structural stability, and consistent performance across full sessions. The needle maintains its edge and alignment throughout extended PMU procedures, reducing the need for mid-session replacements and giving artists uninterrupted creative flow.

Designed for Artistic Freedom

Ocean Heart is built on a core philosophy: find beauty, create beauty, share beauty, become the beauty. The design reflects a deliberate intention to elevate PMU tools beyond pure function — into objects of personal expression, aesthetic identity, and creative confidence.

Every design decision supports artistic freedom: the 0.25mm ultra-slim taper for precision control, the smooth ink flow for uninterrupted performance, the gradient visuals for a tool that reflects the artistry of the person holding it. Ocean Heart is a fashion statement as much as a professional instrument.

Inspired by Global Embroidery Aesthetics

The structural refinements of Ocean Heart — the delicate taper, the precision layering philosophy, the focus on fine detail — were shaped by feedback from world-renowned embroidery artists across the global PMU community. The result is a cartridge that brings the sensibility of fine embroidery craftsmanship to permanent makeup work: precise, refined, and artistically intentional.

Built for Professional Standards

As with any PMU procedure, proper skin preparation, consistent needle depth, and sterile technique are essential for safe results. Ocean Heart cartridges support this workflow with a stable, precision-engineered construction and smooth ink delivery — giving artists reliable control across hairstroke brows, ombré brows, lip blush, and eyeliner work at a professional level.
