BIGWASP Energy Tattoo Cartridge Needles 50pc Assorted 0.35mm Round Magnum RM Set — Finger Ledge, Anti-Backflow

BIGWASP Energy Tattoo Cartridge Needles are a 50-piece assorted pack of finger-ledge, anti-backflow round magnum cartridges (0.35mm) designed for steady grip and consistent ink flow.

These cartridges combine a transparent precision tip, a soft silicone housing and a finger ledge to make handheld tattoo work more controlled and visible. The set includes five round magnum (RM) configurations commonly used for shading and color packing, packaged individually to keep supplies clean and ready. Built with stainless steel needles and PVC components, the cartridges are compatible with most cartridge-style rotary and coil machines that accept standard RM fittings.

What sizes and quantities are included in the 50-piece set?

The pack contains 50 cartridges total, arranged as five types of round magnum groupings. Each type comes as a batch of 10 cartridges, offering immediate variety for shading and blending tasks without buying single packs.

• 10 x 7RM (1207RM)
• 10 x 9RM (1209RM)
• 10 x 11RM (1211RM)
• 10 x 13RM (1213RM)
• 10 x 15RM (1215RM)

How does the finger ledge and grip design help during long sessions?

Each cartridge features a molded finger ledge on the tip grip so artists can hold the machine more comfortably and maintain steadier hand control. That extra surface reduces slippage and minimizes thumb and finger strain during extended shading or color packing tasks.

• Molded ledge for improved finger placement and tactile control
• Soft silicone housing reduces vibration transfer to the hand
• Transparent tip lets you monitor ink movement in the reservoir

Are these cartridges safe from backflow and easy to use with my machine?

BIGWASP Energy cartridges include an anti-backflow membrane and rubber-loaded design to resist ink returning into the tube, helping protect your machine. They use the standard RM connection and 0.35mm needle diameter, so they fit most cartridge-capable tattoo machines that support round magnum configurations.

• Plastic membrane and rubber seal reduce ink backflow risks
• Standard RM fitting for broad machine compatibility
• Individually sealed packaging for hygiene and convenience

What materials and features ensure durability and consistent ink flow?

Needles are stainless steel and housed in a PVC cartridge body with a transparent tip for visible ink flow. This design maintains consistent ink delivery to the needle cluster and offers durability across multiple sessions when used and stored properly.

• Stainless steel needles for strength and consistent penetration
• PVC cartridge housing with a clear tip for visible ink reservoir
• Soft silicone elements for reduced vibration and improved comfort
