This smooth, and durable 12" round salad bowl will be the final touch to your next eco friendly dinner party. Made of bamboo. 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, it has an extensive root system that continually sends up new shoots, naturally replenishing itself, making it one of the most renewable resources known.
