I was surprised when looking around at wedding ring tattoos at how many there are out there. My thought was I would find a few, but the number of them was amazing.
Anyway, here's a couple of them that look pretty good, although the time people spend together seems to be less and less, and the general permanency of a tattoo doesn't seem to go with that idea.
But you can get rid of a tattoo of course, although it's not cheap, and the area of the finger can be a somewhat painful and sensitive spot to be tattooed in, or to have it removed.
It seems like the people getting these have faith in lasting a long time, and that's a good thing.
