I build a lot of different machines with also different designs so , if you work in germany in a tattoo shop there you have to follow the rules itīs called hppc for sterile work so you must have a machine bag and so far... so the design doesnīt matter. With the goldhand hanging from the machine itīs just a "brand" tap only
for 100 % handmade work if someone buy the machine he or she put it in the trash or so this not a machine part.
i am working every day 12 hours with tattoo machine building and i have no time to reply this kindergarten like questions i have to better things.
Videos of all my machines will come to youtube but a day has only 24 hours and i have only two hands, if you are interested in a machine i can send you a video of the machine of your choice.
Sorry for the bad english i am from germany i would wish some more help from some people here on the forum because i donīt understand a lot and then i have
to wait for a friend who speks english and he helps me translate.
