Calaisio Luncheon Napkin Holder 7.75” sq x 2.25”H The artisans, who reside in remote villages in the South Pacific, hand-make each of the products in this collection. The vines they use to construct them- called “vignes d'eau” or water vines- only grow in remote mountain jungles and are very difficult to reach and challenging to harvest. However, once reaped, the vines grow back quickly, leaving no damage in their native forests. At a mere 3 millimeters in diameter the water-vine takes 1-7 days to hand-weave into a finished design but yields a substantially more durable, heat-resistant and elegant product.
