Real Tattoo Artists
Best cartridges I’ve ever used! Others never really felt ‘right’. These feel and line just like regular needles on a bar. Will not use any other needles, plus tattooer-owned and operated.

For the first time ever after purchasing these needles, I feel truly confident in my equipment’s ability to get the job done right. I feel proud to purchase these products again because it truly seems like the people behind this put a whole lot of passion and heart into it.
First time using Maverick, decided to try them out since I see good things posted all the time. Free shipping is awesome to see in this day and age. So far I’ve only tried the T7RL (first time trying a tight liner, definitely felt more like a 5RL lol) and it was great. Didnt think it would be that different from a regular 7RL, but it was definitely much tighter. Held ink greatly, distributed ink nicely, and was nice and stable. The handwritten note and them being tattooer owned, idk what else you want in your cartridge/supplies shop. 10/10 experience and cartridges. Already ordered some curved mags to try.
