And to keep this thread on track I own both ez pen. Hawk style pen. And real hawk pen. They all run great and close to the same. The one thing I found though is even though they all state they have 3.5 mm stroke. It is not true . the real hawk pen is the best. It has the 3.5 mm maybe a bit more the other two were much closer to 3 mm. It isn't a huge difference when u think of .5mm but it does make a big difference while tattooing . especially line work . the real hawk pen is where its at. And you know what buying the knock off first lead me to buying the real one after so both sides win. The end .
