The needle holder is designed for manual tattooing using the HandPoke technique (the handpoke Style is one of the ways to apply body drawings, which consists of two words, which in English mean "hand" – hand, "poke" – to pierce). In this case, you can use any standard spikes on the bars (rods) that are used for standard machines. With any wire cutters, we bite off the desired length from your bar — I think 2 cm from the soldering point of the needles on the bar is sufficient. Untwist 2 hex bolts in the holder and secure the needle.
