BIGWASP Tattoo Cartridge Needles 50pcs Assorted Round Shader 3RS–11RS Sterile Pack with Backflow Protection

BIGWASP 50pcs Assorted Disposable Cartridge Tattoo Needles are a mixed set of #12 standard round shader (RS) cartridges, offering five popular RS sizes for shading and blending in a single sterile, ready-to-use pack.

These transparent disposable cartridges come in a balanced assortment of 3RS, 5RS, 7RS, 9RS and 11RS (labeled as 1203RS, 1205RS, 1207RS, 1209RS, 1211RS), ten pieces per size, totaling 50 sealed cartridges. Each cartridge features a one-way plastic membrane to reduce ink backflow and a rubber band-loaded needle configuration for smooth, consistent performance across most rotary, coiled, and Hawk-style machines. Individually packaged and sterile, they are designed for convenience in busy studios where speed, hygiene, and predictable shading results matter.

How are these cartridges organized and what sizes are included?

Each box contains 50 individually sealed cartridges: ten of each RS grouping, spanning finer to broader round shader configurations for gradual tonal control. The mix makes it simple to switch between delicate fills and broader shading without buying separate packs.

• Contents: 1203RS, 1205RS, 1207RS, 1209RS, 1211RS (10 pieces each)
• Total count: 50 sterile cartridges
• Standard #12 grouping improves compatibility with many grips

Will these cartridges fit my machine and keep ink from flowing back?

Yes — the cartridges are compatible with most rotary and coiled tattoo machines as well as Hawk needle systems that accept standard cartridge fittings. Each unit includes a plastic membrane and rubber band loading to help prevent ink from migrating into the tube and drive area.

• Fits: rotary, coiled, and Hawk-style cartridge machines
• Backflow protection: built-in plastic membrane
• Needle loading: rubber band system for stable travel

What performance can I expect for shading and blending?

The RS (round shader) configuration in graduated sizes gives consistent pigment delivery for soft fills, gradients, and textural shading. The transparent housing helps you monitor ink flow and needle movement, supporting predictable results during longer shading passes.

• Use cases: soft shading, color packing, gradient fills
• Transparent cartridge body for visual ink monitoring
• Stable needle alignment for even pigment distribution

Are these cartridges safe and ready to use out of the package?

Each cartridge is individually packed and sealed for hygienic storage until needed. While designed for single use, proper studio protocols still apply: open only at the bench, discard after one client, and follow local health regulations.

• Packaging: individually sealed sterile cartridges
• Single-use: designed for one client/session only
• Storage: keep in a cool, dry place until opened

Who is this for: This assorted 50-piece set is geared toward professional tattoo artists and apprentices who need a compact, versatile supply of round shader cartridges for everyday shading, color transitions, and touch-ups. It also suits mobile artists or studios that prefer to stock a range of RS sizes in one convenient box for quick swaps during sessions.
