Trace the tide. The Coastlines press-on nail set draws its inspiration from the edge of land and sea, with layered blue crosshatched tips that mimic the pull of tides and a sculpted 3D accent that nods to windswept shells. A soft nude base mirrors sun-washed sand, while the medium almond shape and high-gloss finish give it a polished, windswept look. It’s shoreline detail, drawn fingertip by fingertip.
