Buttons are almost as old as civilization itself, but they were used primarily for decorative purposes until the 13th century, when the invention of the buttonhole CHANGED EVERYTHING. The single-centimeter, four-hole cast button was adopted as a standard component in men's shirting around the turn of the last century. Its small size, universal shape, and pre-existing holes all lent themselves to being re-purposed as a beautiful, simple bracelet. (And necklace - this piece has been a best-seller of ours for years now.) Here, we've ingeniously wound the chain through the four buttonholes so the button is held flat against the skin. An extra length of larger-link chain at the end of the bracelet allows you adjust the size from 6" to 7.5", or anywhere in between. Available in sterling silver or gold-plated brass with a gold-filled chain.
