Ondula is a round fruit bowl, made of blue-tinted steel baked with epoxy resin The material it creates vibrates from the central truncated cone to the raised edges in concentric circles moved by a drop. Produced by Alessi, it measures 31.5 cm in diameter and stands 6.1 cm tall. Looks also great hung on the wall. Very good condition, only very light scratches on button only visibel from very close distance, see last picture. Last month I added black felt slides to for protection, they can be easily removed with no damage. Very rare, only produced for a short time. Made in Italy Design by Achille Castiglioni in 1996
