Sparkle Stool by Kartell. Tokyjin Yoshioka's new Sparkle stool and table collection are as striking as a brilliant ray of sunlight. The plastic's unique pleating (both inside and out) is reflected in the end result: two new jewels for the home, that look like precious gems... diamonds or sapphires, emeralds, topaz or rubies, depending on the colour chosen. Can also be used outdoors and are scratch and impact-resistant. Sparkle Stool by Kartell is designed by Tokujin Yoshioka.
