INKin Ball Point Pen Tattoo Cartridges 50Pcs Mixed Practice Ballpoint Tattoo Cartridges Needles with Membrane Tattoo Ball Pen Cartridges for Dotwork Drawing Practice on Papers

Need I say any more? These needles are awesome. I get them every chance I can. I love using them. They work great in my machine. A little expensive, but worth it. Too bad I can't get free merchandise for reviews! lol

These cartridges are a fun practice tool. I use them in my Axys Valhalla and they fit perfectly. The cartridges don't last a long time, but enough you should get a drawing out of them or 1-2 hours of straight practice with lining or shading. They also arrived individually wrapped which is nice too! All in all great product and do recommend to friends and other apprentices.

Fits in the generic brand tattoo machine I have. Ink lasts a while. I love using these for my art :)

I bought these for practice but unfortunately they're only good for about one use. I figured they would last about as long as a small average pen, but I was only able to use one pen for one page of drawing. The one page I did do was very minimal and didn't even use much ink at all, it was basically just scribbles. Even though they are listed at a good price, the quality just isn't there. You get what you pay for with these. I would not recommend this brand.

Super good to practice with recommend thick paper to use these with

Needed this to practice my lines. Works good and packaged like the regular needels.

Good for practicing tattooing without risking making any permanent mistakes on skin. A safe and inexpensive way to get a feel for tattooing. Plus you don’t have to waste tattoo ink, fake skin or real cartridges. Convenient

The consistency of these cartridges left something to be desired.There were moments when they worked well, and I was able to practice my tattooing techniques smoothly. But there were also times when the ink flow wasn't as smooth or consistent as I would have liked. This inconsistency was a bit frustrating.Despite the occasional mishaps, I do see the potential in these cartridges. The idea of using a ballpoint pen for practice is clever. They could use some refining though.
