Ballpoint Pen Cartridges – Original Black Ink (6-Pack) – Tattoo Practice Cartridges for Rotary Tattoo Machines – Oil-Based Ink for Creating Flash Art – Fake Skin Alternative

Work awesome. Fits my tattoo machine, and has been perfect for practicing my linework without having to use up my practice skins or needles/ink. I've done several small linework pieces on the practice paper and it still has ink. The colors dark enough. Easy to install easy to use. Feels pretty close to the real thing.

Enjoy using this product. Not a tattoo artist but enjoyed having fun with these

These definitely helped my husband practice on tattooing. The only problem is, they don't really work on skin and it's a different texture doing it on paper.

Honestly opinion great idea but they sucked to be honest. Durability Lasts a few minutes than runs out. Color Great but runs out so quickly I literally didn’t get to draw much Refill That I know of there’s no way to refill Functionality It works but short term very short maybe you might line a piece but you won’t get to shade it Value It’s a rip off the way it runs out and for the price I’d rather sit with a dollar store pen and just make dots myself. I’m an artist and I feel like it was a waste of money. Like I said great idea but poor execution. Maybe if they worked on it a little more they might make something better. If you want to get better at tattoo stick to fake skin there’s very good quality stuff on here. But this product isn’t good. I was really excited but quickly disappointed.

This is great for the money, last two hours of sketch time, feels just like using a needle to practice. Size fit my tattoo pen and functioned with no problems. Easy to use just plug and play, quality ink disperses evenly. Seems very durable and like it would fit many different tattoo pens.

When the ink comes out properly then it works great but the ink tends to stop coming out and takes FOREVER to start working properly again. It happens A LOT.

This is a great product for when you’re wanting to learn tattooing. You get a decent amount for the price !

So cool
