HAWINK 7RL Tattoo Needle Cartridges 50pc — 7 Round Liner X-Taper with Sterile Membrane

HAWINK 7RL cartridges are single-use, X-taper 7 round liner tattoo needle cartridges in a box of 50, engineered for precise lining and reliable ink flow with a built-in membrane to prevent backflow.

These disposable tattoo needle cartridges are designed for professional artists who need consistent, sterile performance and easy handling. Each cartridge uses a medical-grade 316 stainless steel tip and a durable plastic body with a silicone suspension to keep needle movement responsive. The semi-transparent, bevel-style tip gives clear visibility of needle action and ink, while individual EO gas sterilization and a leak-preventing membrane protect your machine and client.

How do these cartridges improve lining precision?

The 7 round liner (7RL) configuration groups seven needles tightly for clean, consistent lines. The X-taper needle geometry concentrates pigment delivery through a sharp point, aiding crisp edges and smooth stroke transitions. Together with the silicone elastic hold, the needle returns behave predictably for controlled work.

• 7 tightly grouped needles for uniform line width
• X-taper tips for focused pigment placement
• Silicone suspension for steady needle rebound
• Bevel tip visibility for better stroke control

Are these cartridges safe and ready for professional use?

Every cartridge arrives individually sealed and sterilized by EO gas to industry standards. The built-in membrane blocks ink and fluid from entering the tube or machine, lowering contamination risk and machine maintenance. Materials are selected for hygiene and durability without assuming medical claims.

• Individual sterile packaging (EO gas)
• Membrane to prevent backflow into the machine
• 316 stainless steel needle tips and medical-grade plastics
• Disposable single-use design to maintain hygiene

Which machines and grips are these HAWINK cartridges compatible with?

HAWINK cartridges are built to fit most rotary and coil machines that accept cartridge-style needles, including Hawk-compatible grips and standard cartridge systems. This universality makes them a flexible choice for artists who switch setups or collaborate in different studios. Check your grip or machine manufacturer guidance for cartridge fit compatibility when in doubt.

How do I choose the right needle taper and size for my work?

X-taper liners like the 7RL are suited for artists aiming for sharp, concentrated lines and detail work. If you prioritize softer, more diffuse lines, consider round shaders or magnum configurations instead. Always match needle choice to the style, skin type, and machine setup to achieve the intended result.

• X-taper: precision and concentrated ink deposit
• 7RL: ideal for medium-to-fine linework and details
• Alternate sizes/tapers for shading or softer lines
• Test on practice skins to confirm machine tuning and feel

Who is this for? Tattoo professionals and experienced apprentices who need a dependable, sterile supply of liner cartridges for everyday studio work will find the HAWINK 7RL 50-pack useful. It's particularly suited to artists performing precise lining, lettering, and fine details who prefer disposable cartridges with visible tips, a silicone-stabilized needle action, and anti-backflow protection for cleaner sessions and less machine maintenance.
