Big Wasp X RS Cartridge Needles

Complete guide: Big Wasp X RS Cartridge Needles

Big Wasp X Series Round Shader cartridges are disposable tattoo needles designed for fine shading, blending, and pepper shading in small and medium areas. The circular needle formation, with wider spacing than a liner, deposits ink in a controlled manner — exactly what you need for subtle textures, portraits, or shading in tight spaces where a magnum would be too wide. They are made from 316L stainless steel, with a transparent medical-grade plastic body and an anti-reflux silicone membrane, supplied in a box of 20 pieces individually sterilized with EO gas. They fit most pen-style rotary machines and are useful for both experienced artists and beginners building their basic kit.

How to use

1. Wash your hands, put on disposable gloves, and prepare the workstation with protective barriers: wrap the machine and grip in film, clean work area.
2. Check the individual sterile packaging of the cartridge — if it is open, punctured, or damaged, do not use it and switch to another one from the box.
3. Remove the cartridge without touching the tip and secure it in the grip of the rotary machine until it locks firmly.
4. Adjust the needle depth from the grip and set the voltage according to the technique — as a guideline, according to the manufacturer: 5.5–7 V for pepper shading (3RS–5RS), 7–8 V for standard shading (5RS–7RS), 7.5–8.5 V for dense shading (7RS–9RS); on machines with a long stroke, lower the voltage.
5. Test first on synthetic skin: observe the ink flow through the transparent body and adjust your hand speed before working on the client.
6. Dip the tip into the pigment cup and work the shading in controlled motions; re-dip often — an RS covers smaller surfaces than a magnum, so it uses up ink from the tip faster.
7. At the end of the session, remove the cartridge and discard it in the sharps container — it is a disposable product.
8. Disinfect or sterilize the grip according to your usual procedure before the next session.

Tips from us

• Start with 5RS and 7RS — they are the most versatile configurations; 3RS is for ultra-fine details and texturing, 9RS for slightly larger areas that still require precision.
• Practical rule for selection: areas under approximately 3 cm width → RS; over 3 cm → magnum (RM/M1), which covers faster.
• RS is more sensitive to voltage than a magnum — small changes are immediately visible in saturation, so adjust gradually and note down the settings that work for you.
• The silicone membrane reduces ink reflux toward the machine, but does not replace protective barriers — use them for every job.
• Take advantage of the transparent body: if you see the ink flow decreasing, re-dip the tip in pigment instead of pressing harder on the skin.
• Keep the box in a dry, clean place, with individual packages intact until the moment of use.
