What Are Kwadron Needles? (Cartridges + Traditional, in Brief)

Kwadron is known worldwide for creating exceptional tattoo needles artists rely on, thanks to the high-quality surgical steel and stabilization system. Both their traditional bar-mounted needles and cartridges offer expert precision and a variety of configurations, ensuring artists can create their best art yet. 

Kwadron Cartridge Needles

Kwadron cartridge needles are designed with artists in mind, using a unique stabilization system, a safety membrane to prevent ink and blood backflow, and a medical-grade plastic housing. The result is expert control at every stage, whether you're creating crisp, bold linework or heavily packing in color. Find everything from a Kwadron needle 1RL to a Kwadron cartridge needle curved magnum soft edge, along with PMU cartridges. 

Kwadron Traditional Needles

You can expect the same ultra-sharp needles and epic quality from their lineup of traditional needles, which come in a range of sizes that allow you better control of your configurations. 

Their lineup includes round liners and shaders, soft edges, and magnums.

Cartridge vs. Traditional: Which Kwadron Format Do You Need?

Choosing between Kwadron cartridge needles and traditional needles comes down to the type of machine and setup you prefer. 

Traditional needles are pre-soldered on a long bar that must be inserted into a tube and grip (meaning it requires manual assembly). Manual assembly takes longer, which may not be ideal if you need to change needles mid-session. They are compatible with coil machines and often cost less than cartridges. 


Cartridges are a group of needles pre-assembled inside a plastic casing. Most feature a membrane to prevent backflow, improving hygiene and safety in the process. They're incredibly easy to snap into a traditional rotary or pen-style machine, offering superior speed.


Pair the right type of Kwadron needles with a compatible machine: traditional needles for coil machines and cartridges for rotary machines. Think about which machine is most comfortable for you and whether you prefer the tactile feel of a coil machine over the speed and convenience of a rotary machine.  

Quick Tips for Choosing Your Configuration

The type of configuration you need for your Kwadron tattoo needles depends on what you're trying to achieve as you create each part of the tattoo. Here’s a quick breakdown of each type of needle:

  • Round liner: The needles are grouped in a tight circle and best for all types of linework, including both fine and bold lining. 

  • Round shader: Also grouped in a circular cluster but with wider spacing and good for soft shading and thick linework. 

  • Magnum: With two rows of needles, these are best for large areas of shading and color packing. 

  • Curved magnum: The curved shape makes these needles ideal for soft shading.

  • Flat: Needles are grouped in a straight line, making them good for bold lines and geometric work. 


Kwadron Sublime cartridge tattoo needles are available for magnum configurations and designed with a flat bottom to prevent the needle from bending or twisting.
