Kwadron Cartridges for PMU and Tattoo

Kwadron cartridges are professional needle cartridges used with rotary PMU and tattoo machines for permanent makeup, microblading-style machine work, and tattoo procedures. This collection carries the full Kwadron cartridge range available at Beauty Hunter: standard Kwadron cartridges and the PMU Optima line, in a range of needle configurations, gauges, and taper types, available as single cartridges and in 20-piece sets.

Products are suited to licensed PMU artists, permanent makeup technicians, and tattoo artists who use rotary machines with cartridge needle systems. Kwadron is a professional needle brand used in PMU and tattoo settings. All cartridges in this collection are single-use disposable products.

Kwadron Cartridge Lines and Needle Configurations

The collection includes two Kwadron product lines — Standard and PMU Optima — across several needle configurations. Understanding the needle code system is essential for selecting the correct cartridge for the technique and area being worked.

Reading the Kwadron Needle Code

Each Kwadron cartridge is identified by a code that specifies the needle gauge, needle count, configuration type, and taper. For example, 25/3 RLLT means: 0.25 mm gauge, 3 needles, Round Liner, Long Taper.

• Gauge (first number) — the needle diameter in hundredths of a millimeter. Available gauges in this collection: 20 (0.20 mm), 25 (0.25 mm), 30 (0.30 mm), and 35 (0.35 mm). Finer gauges (20, 25) produce finer lines and are suited to delicate PMU work. Wider gauges (30, 35) suit bolder lines and shading.
• Needle count (second number) — the number of needles in the cartridge: 1, 3, or 5. A single needle (1) produces the finest, most precise line. Three needles (3) suit liner and light shading work. Five needles (5) suit broader coverage and shading.
• Configuration type — RL (Round Liner), RS (Round Shader), RSLT (Round Shader Long Taper), RSPT (Round Shader Point Taper). Round Liners are suited to line work; Round Shaders are suited to shading and filling.
• Taper — LT (Long Taper), MT (Medium Taper), T (Textured). Long taper needles have a longer point, which can affect ink flow and precision. Medium taper is a standard working taper. The RLLT-T variant (35/1) adds a textured finish to the long taper needle.

The taper and gauge together determine how the needle interacts with the skin and how ink or pigment is deposited. Always select based on the technique, the area being worked, and the machine being used.

Standard Kwadron Cartridges

The standard Kwadron line covers a range of configurations suited to both PMU and tattoo work.

• RL (Round Liner) — 25/1, 25/3, 30/1, 35/1. Standard round liner configuration for line work.
• RLLT (Round Liner Long Taper) — 25/3, 25/5, 30/3, 35/3. Long taper round liner for finer, more precise line work.
• RLMT (Round Liner Medium Taper) — 35/1. Medium taper single-needle round liner.
• RLLT-T (Round Liner Long Taper Textured) — 35/1. Long taper with a textured needle surface.
• RS (Round Shader) — 25/3, 30/3, 35/3. Standard round shader for shading and filling.
• RSLT (Round Shader Long Taper) — 25/5. Five-needle round shader with long taper for broader shading coverage.

PMU Optima Cartridges

The PMU Optima line is specifically positioned for permanent makeup applications. It is available in finer gauges (20–35 mm) and focuses on round liner and round shader configurations suited to PMU techniques including eyebrow, eyeliner, and lip work.

• PMU Optima RLLT (Round Liner Long Taper) — 20/1, 20/3, 25/1, 25/3, 30/1, 35/1. The widest configuration range in the PMU Optima line, covering single and three-needle options across all four available gauges. The 20-gauge options are exclusive to the PMU Optima line and are the finest available in this collection.
• PMU Optima RSPT (Round Shader Point Taper) — 30/3. A three-needle round shader with point taper, suited to shading in PMU procedures.

The PMU Optima line's inclusion of 0.20 mm gauge cartridges makes it the choice for the finest PMU line work available in this collection. The point taper (RSPT) is a distinct taper type not available in the standard line.

How to Choose Kwadron Cartridges

Selecting the right Kwadron cartridge depends on the procedure, the area being worked, and the desired result.

• Procedure type — for PMU eyebrow, eyeliner, and lip work, the PMU Optima line is specifically positioned for these applications. For tattoo line work and shading, the standard line covers a broader range of configurations.
• Line fineness — for the finest PMU lines, select a lower gauge (20 or 25) with a single needle (1) and long taper (RLLT). For bolder lines, select a higher gauge (30 or 35) with more needles.
• Shading vs. lining — Round Liners (RL, RLLT, RLMT) suit line work. Round Shaders (RS, RSLT, RSPT) suit shading, filling, and soft powder effects.
• Needle count — single needle (1) suits the most precise line work. Three needles (3) suit liner and light shading. Five needles (5) suit broader shading coverage.
• Single vs. set — single cartridges (1 pc) suit technicians who want to test a configuration before committing to a full set, or who use a given configuration infrequently. Sets of 20 pcs are more economical for configurations used regularly in daily practice.

For a core PMU cartridge setup, stocking the PMU Optima RLLT in the gauge and needle count suited to the primary technique, plus a round shader for powder and shading work, covers the requirements for most PMU service menus.

How to Use Kwadron Cartridges

Kwadron cartridges are used with compatible rotary PMU and tattoo machines that accept standard cartridge needle systems. Each cartridge is single-use and must be discarded after each client. The cartridge is inserted into the machine grip, the needle depth is set according to the technique and skin type, and the machine is operated at the speed and voltage appropriate for the cartridge configuration and procedure. Always follow the machine manufacturer's instructions for cartridge compatibility and the Kwadron guidelines for the specific cartridge type.

Professional Brands

This collection carries cartridges exclusively from Kwadron, a professional needle brand used in PMU and tattoo settings. Kwadron's range in this collection spans two distinct product lines.

The Standard Kwadron line covers six configuration types (RL, RLLT, RLMT, RLLT-T, RS, RSLT) across gauges 25–35 and needle counts 1, 3, and 5. It is suited to both PMU and tattoo work and provides the widest variety of configuration types in the collection, including the textured RLLT-T and the five-needle RSLT.

The PMU Optima line is specifically positioned for permanent makeup and covers two configuration types (RLLT and RSPT) across gauges 20–35. The inclusion of 0.20 mm gauge cartridges — the finest available in this collection — and the point taper (RSPT) distinguish the PMU Optima line from the standard range. The PMU Optima RLLT is available in the most configurations of any single cartridge type in the collection: six gauge and needle count combinations.
