Our Bamboo Bowl Set is simple, modern and elegant. Each bowl graduates into a larger bowl with the widest bowl 5 inches in diameter. Hand-crafted from lightweight, pressed bamboo, it is lightly textured, but smooth to the touch and light chocolate in color. Bamboo is one of the most environmentally friendly and renewable resources in the world. Bamboo is actually a grass that grows to a harvestable height between 3-5 years. Some species grow up to 2 feet per day. After harvesting bamboo does not require replanting as it has an extensive root system that continually sends up new shoots naturally replenishing itself. Bamboo holds the promise of a sustainable cost effective and ecologically responsible alternative to the widespread clearcutting of our old growth forests. In the kitchen, bamboo is preferred by professional chefs because it's much harder than the maple traditionally used even for cutting boards. Our beautiful Salad Bowls are durable and hardy enough to remain unmarred and lovely for years to come making them the ideal gift for your favorite chef. For easy care wash with a mild detergent and warm water- no dishwasher. Does not require re-oiling. Foodsafe and waterproof. Largest bowl measures each measure 5" D x 2.25" H.
