Matching tattoos make a great way for a couple to make a show of their dedication and commitment to each other, but they are not just confined to couples in a relationship, like husband and wife or lovers.
Compass and Anchor Tattoo. Could be best friend or couple tattoo. The anchor would be to hold the other no matter what happens, no matter what big storms come their way. & the compass is of course, to be the one to guide each other.
