Assorted 50pc Tattoo Cartridge Needles 0.35mm Mixed Round Magnum

In this review the BIGWASP Energy 50pc assortment is evaluated for artists who need reliable cartridge needles for line and shading work. The bottom line: this pack is best for tattooists who value comfort during long sessions and consistent ink flow; the single biggest reason to buy is the finger ledge and transparent tip that make handling and ink visibility noticeably easier. The review considers build, usability, and typical studio concerns like backflow protection, and it reflects hands-on impressions and reported customer feedback.

Key Features

• Assorted pack: The set contains 50pcs with 10pcs each of 1207RM, 1209RM, 1211RM, 1213RM and 1215RM, giving a useful spread of round magnum sizes for different tasks.
• Comfort finger ledge: Each cartridge has a finger ledge on the tip grip that improves hold and reduces strain, helping artists keep a steady hand in longer sessions.
• Transparent precision tip: The clear tip improves visibility of ink in the reservoir so the artist can monitor inkflow and saturation during use.
• Anti-backflow design: Rubber band loaded cartridges with a plastic membrane help prevent ink from flowing back into the machine tubes, improving hygiene and reducing mess.
• Durable materials: Cartridges are made from PVC and stainless steel, providing reliable build quality and single-use sealing for safety and convenience.

Who It's For

This set is aimed at professional tattoo artists and dedicated apprentices who need a broad range of round magnum sizes for shading and filling, and who prefer cartridges with a finger ledge for better ergonomics. The clear tip and anti-backflow features suit busy studio work where consistent inkflow and cleanliness matter.

Artists seeking specialty configurations beyond round magnums or those who require nitinol or specialty alloy needles should look elsewhere; also, those strictly avoiding any reports of occasional ink spitting may prefer cartridges with different reservoir designs.

Pros & Cons

Cons

• Some users report occasional ink spitting with certain inks or machines, so expect to test ink compatibility first.
