Needle cartridge for tattoo machine is a module that doesn't require additional assembly or sterilization. It is welded together needles placed in a plastic housing, precision molded and engineered to maximize accuracy and consistency. Tattoo needle cartridges allow tattoo artists to set up needles and switch needle configuration very quickly during the tattooing process.

Accurate selection of all the details for a particular type of work (painting, shading, creating a contour) is the guarantee of a quality tattoo. A specific set of needles is recommended for each type of work.

Round Magnum Tattoo cartridges are similar to a Standard Magnum Tattoo cartridge except the ends of the needles are curved in a quarter moon shape instead of being straight across. This is used to create less trauma to the skin for tattooing with magnums type tattoo needles. Many artists worldwide prefer this type of cartridge over a straight magnum today. Round magnum shaders come in various sizes, from a 3 (three needles grouped together) to a 15. Round shaders hold more ink and are moved in a circular motion no more than three times in an area to fill in the area with color. Round Magnum cartridges will be especially convenient for the aspiring tattoo artists: their use is safe. They allow you to make uniform shading, smooth transitions between the elements and soft feathering. With a round magnum, the arch of the needle will allow you to move more freely on the skin without the risk of the edges digging in.

Each cartridge comes in a Sterile Pouch with the type of needle, lot no., expiration date, and compatible tip/tube printed right on the outside. The cartridges are EO (Ethylene Oxide) gas sterilized and should only be used if the package is undamaged. Round Magnum tattoo needles are made of stainless surgical steel and packed in sterile packaging.
