The Mermaid with Harp strums away beneath the waves, proving acoustics are a problem for landlubbers to sort out. This temporary tattoo lasts up to 2 weeks, so you can try the look before you book the artist. Made for ocean dreamers and bold, detailed blackwork fans who love a bit of myth with their ink. At 6 x 8 cm, it sits beautifully on your forearm or thigh, worn solo or layered with other pieces from our collection.
