How many kinds of tattoo needles are there?

The smallest needle mouth is a three-needle mouth, and all three needles can be used.

Then you can prepare a 5 7 9 universal one.

Then get a 14 needle.

The above is the needle mouth for thread cutting. Just prepare two of each. I mean stainless steel.

The smallest needle row is X5, which is rarely used for small parts. Circle 7 or 9 is enough.

Secondly, X7, you have to keep two of these.

X9 two

X 15 does not make much sense. Why not just row X23 X39? These are all suitable for large-area plate fog. One for each sample. There is no disposable needle mouth, and disinfection tools are ready.
