This beautiful mussel shell button adds a natural touch to your next knit, crochet, or sewing project. Each one measures 20mm and is sold individually - perfect when you only need a few to complete a look. The front features a smooth, glossy finish in pale, iridescent tones with unique cream, gray, and violet streaks complemented by a natural textured back. With two holes for secure stitching, this button combines beauty and function. No two are exactly alike- just like shells on the shore.
