From the Cleverly Sustainable Collection. Cleverly Sustainable utensils utilize handles that are made using 50% less virgin plastic; replacing it with a non-fossil based, reusable waste material known as wheatstraw. Wheatstraw plastic is a biobased plastic made of 50% wheat straw, 49% plastic, and 1% colourants. Wheat straw is what`s left over after harvesting & processing wheat. This resource is readily available worldwide which makes it truly sustainable! The flat silicone whisk was specially developed for whisking sauces and liquids in shallow pans. It is dishwasher safe and comes with a five-year guarantee. Designed by Zyliss in Switzerland, characterized by Swiss elegance and functionality.
