HAWINK 60-Piece Tattoo Needle Cartridge Kit 0.3mm — Assorted Bugpin Round Liners & Round Magnums, EO-Sterilized

HAWINK 60-piece assorted disposable tattoo cartridge kit delivers a versatile mix of 0.3mm round liner and round magnum cartridges for precise lining and smooth shading.

This kit is assembled for artists who want a ready supply of commonly used needle configurations without sorting single cartridges. It combines multiple round liner (RL/Bugpin) sizes and round magnum (RM) sizes in one sterilized box, letting you switch quickly between tight detail work and broader color packing. Each cartridge is EO gas sterilized, fitted with a silicone membrane to reduce backflow, and built with medical-grade stainless steel tips for reliable performance.

What needle sizes are included and how are they arranged?

The set contains 60 disposable cartridges in a specific mix of round liners and round magnums to cover detail and shading needs. The assortment is grouped to give a balance of fine liners and larger magnums for core tattoo workflows.

• Round Liner (Bugpin) sizes: 3RL x8, 5RL x8, 7RL x8, 9RL x8, 11RL x4
• Round Magnum sizes: 9RM x8, 11RM x4, 13RM x4, 15RM x4
• Needle diameter: 0.3 mm (consistent across cartridges)

How do these cartridges prevent ink leakage and maintain hygiene?

Each cartridge includes a silicone membrane and semi-transparent housing that minimize ink backflow while allowing visual inspection during use. All cartridges are individually packaged and sterilized using ethylene oxide (EO) gas for single-use safety.

• Silicone membrane reduces the chance of ink reaching the machine or tube
• Individually sealed packaging ensures sterility until opened
• Semi-transparent tip helps monitor needle movement and ink flow

Are these cartridges compatible with my tattoo machine and what materials are used?

These HAWINK cartridges are designed to work with most rotary and coil machines that accept standard cartridges, including Hawk grips and machines. The needles are stainless steel and the cartridge bodies are made from durable medical-grade plastic for consistent fit and feel.

• Needle tips: 316 medical-grade stainless steel for corrosion resistance
• Other metallic parts: 304 stainless steel where applicable
• Cartridge body: medical-grade plastic with high-quality silicone components

How will this kit streamline my tattoo workflow?

Keeping a comprehensive mix of liners and mags in one box reduces time spent switching supplies mid-session and eliminates frequent reorders for common sizes. The variety supports both fine-line and color/black shading without carrying multiple single-size packs.

• 60 cartridges provide longer session coverage and multiple client appointments
• Assorted sizes cut down on needle changes and workflow interruptions
• Disposable format simplifies cleanup and maintains studio hygiene

Who is this for: Tattoo artists, apprentices, and studios that need a ready-to-use supply of mixed cartridge needles for everyday tattooing. This kit is especially useful for artists who work across styles—tight liners, dotwork, and color filling—who appreciate pre-sterilized, disposable cartridges that fit mainstream grips and machines. It’s also practical for training environments where varied needle sizes are required for practice and instruction.
