I would advise against any tattoo unless u are complete sure about
The design, its meaning and its relevance in your life.
An all but forgotten practice is to use a pen to etch a rough draft
And wear it for a couple days just to see how it feels.
There's also Henna which is semi-permanent, and lasts about 6 months.
Keep thinking about it. If u are asking for advice on an internet forum,
You probably aren't ready for it.
