Let customers speak for us
Voici la traduction en anglais :
Still just as impressed with this needle bar quality! Everything is wrapped with incredible precision and insane smoothness! Best needle brand I work with! Can’t wait to see bigger configurations!
Metrix Curved Magnums are very consistent and smooth. Perfect for soft gradients and large black & grey work. The grouping is stable and the needle flow feels controlled. Great quality.
I first discovered Metrix via their stencil primer. Now the only primer I use. Got curious and discovered they made cartridges. Ordered some and was just as impressed. Not only are they top tier quality cartridges, unlike so many brands today, they are affordable! Even with paying customs to have them shipped to the US. Still cheaper than many cartridges you can order from companies direct in the states. Buy them and try them and you will see for yourself. You won't be disappointed.
I’ve been using Metrix cartridges since the very beginning, and what truly sets them apart is not just where they started, but how consistently they’ve evolved. With every upgrade, you can feel the refinement: smoother flow, cleaner saturation, stability in the hand, and reliability that shows up exactly where it matters most, on the skin.
Beyond the product, I have deep respect for the people behind Metrix. The owners have been working relentlessly in our industry, staying present, listening to artists, and refusing to compromise on quality. That kind of dedication shows in every cartridge they put out.
Metrix is not chasing trends, they’re raising standards.
LITOS APPROVED ✅
The slam liners I've been sent are some of the best ive used for bold and crisp traditional lines. From the 7's to 18's ive tried them all and doubt I will be using any other needles from now on.
These are frkn amazing 😊
Absolutely love these for both fine lines and super intricate shading
We order from the United States because this is the best we have found. It does an outstanding job and we are excited to have found a product that meets all of our needs when primer is needed. Thank you!
Amazing needles ! 14 slam liners I use and can’t recommend enough for bold traditional 🔥
Metrix never lets me down, crispy lines packed efficiently into the skin, minimal trauma during in-skin times, rarely ever spit and no rattling! Will always be loyal to Metrix Signature’s.
And of course A+ customer service.
Love this brand so much!!!! For so long I was stuck with needles that rattled in the tube, cartridges that weren’t assembled properly due to manufacturing. Metrix is solid and reliable. With every order I know I’m getting the best quality and can rely on them for any needle size
Just try it. You won’t regret it. Worth every penny.
I've test a lot for needles but the metrix are for me, the best to use, they are smooth for the skin and they have perfect precision
"I'm thoroughly impressed with Metrix tattoo needles! The smooth, precise puncture and consistent ink flow have significantly improved my work. The needles are durable, well-balanced, and easy to maneuver. Highly recommend for artists seeking top-notch quality
The best trad grouping around
So many tattooists are making their own cartridges and they seriously lack the quality of Metrix. Thank you for such a great product!!!!
