BIGWASP Energy Tattoo Cartridge Needles 50pcs Assorted 0.35mm Round Liner Set with Finger Ledge & Anti-Backflow

BIGWASP Energy Tattoo Cartridge Needles are a 50-piece assorted set of round liner cartridges (3RL, 5RL, 7RL, 9RL, 11RL) with finger ledge grips, anti-backflow membrane, and clear tips designed for steady ink flow on rotary tattoo machines.

Designed for tattoo artists who want reliable round liners in multiple sizes, this BIGWASP kit contains ten of each common liner size in a standardized 0.35mm configuration. The cartridges combine a transparent precision tip for visual ink control, a silicone finger ledge for improved handling, and an anti-backflow membrane to protect your machine and maintain hygiene. Each cartridge is sealed and disposable for convenient single-use work sessions.

How do these cartridges improve control during detailed lining?

The integrated finger ledge offers a tactile rest point that helps stabilize the hand and reduce fatigue during long sessions. The grip makes it easier to hold the cartridge closer to the skin for precise line work, and the consistent factory assembly reduces wobble between needles.

• Finger ledge on every cartridge tip improves grip and comfort
• Consistent 0.35mm needle diameter across sizes for predictable lines
• Individually sealed cartridges for clean, ready-to-use performance

Will the clear tip and anti-backflow design help with ink flow and hygiene?

The transparent precision tip makes it easier to watch ink moving through the reservoir, aiding visual control of ink flow. A built-in plastic membrane prevents ink backflow into the tube, which protects the machine and reduces contamination risk, while the rubber-loaded construction maintains steady ink delivery.

• Clear tip gives visual confirmation of ink feed
• Plastic membrane blocks backflow into the machine
• Rubber-loaded cartridge supports consistent ink pressure

What needle sizes are included and when should I choose each one?

This set includes 50 cartridges: ten each of 3RL, 5RL, 7RL, 9RL, and 11RL, covering fine to medium lining needs. Smaller RL sizes (3RL–5RL) are ideal for delicate details and tight lines, while larger RLs (9RL–11RL) are better for thicker outlines and faster coverage.

• 3RL, 5RL — best for fine detail, small scripts, and delicate linework
• 7RL — versatile mid-size liner for general outlining
• 9RL, 11RL — wider liners for bold outlines and quicker passes
• Ten cartridges per size for consistent availability during sessions

Are these cartridges compatible with most rotary tattoo machines and safe to use?

BIGWASP Energy cartridges are designed for standard push-fit rotary tattoo machines that accept disposable cartridge needles. The use of stainless steel needles and PVC housing, along with individual sterile packaging, helps ensure durability and single-use safety; follow your usual sterilization and disposal protocols.

• Standard cartridge format fits most rotary tattoo machines
• Stainless steel needles with PVC housing for durability
• Each cartridge is individually sealed for hygienic single use

Who is this for: This 50-piece BIGWASP Energy kit suits tattoo apprentices building a starter stock, freelance artists who need a range of liner sizes for walk-in work, and professional studios that prefer disposable cartridges with clear tips and enhanced handling. It’s especially helpful when you want predictable ink flow, a tactile grip to reduce hand strain, and a selection of round liners to cover fine to bold outlines without buying separate packs.
