Vulcanised Bamboo is a true alternative to plastic. It is dishwasher-proof and non-toxic. It is made from bamboo sawdust, rice, corn starch and natural plant ties. This material does not contain toxic substances that can be found in many plastic. The stainless steel, we use consists of at least 93% recycled content. An extensive selection of 20 kitchens utensils allows you a wide choice. You are a great combination of style, sustainability and value. We recommend cleaning by hand, but they are dishwasher-proof. Do not let the knife in the dishwasher and dry it by hand. Remove rust stains with a soft cloth and stainless steel polish. Not suitable for use in microwave ovens.
