The new cartridge tattoo needle by TatSoul has some nice features. Having used their quality, smooth running needles in the past I had to try this cartridge with a soft silicone finger ledge. It's like a squishy pencil holder.
What I found a huge plus is the way the Envy finger ledge integration fits into the pen style tattoo machine making it easy for the way I wrap my machine for cross-contamination prevention.
Another style needle cartridge is the Vertix tattoo needle cartridges. Both the TatSoul and Vertix tattoo cartridge needles are great quality, have a lip on the cartridge making it fit nicely up to the edge of the machine tip, and they both have a membrane that prevents the backflow of ink into the machine.
