FAQs
How long does the ink reservoir last?
60 Minutes
Is it possible to swap the ink cartridges on the same needle?
Yes, the cartridges are interchangeable. You just need to clean the needle first to remove any previously used ink color.
Is it true that it tattoos more precisely than a conventional needle?
Is it true that it tattoos more precisely than a conventional needle? Yes, it is completely true, since by reducing the diameter of the hole through which the needle moves, it oscillates less from side to side, allowing for a more precise design.
