The palm handle is made of 100% sustainable natural bamboo wood. It is naturally antibacterial and anti-fungal, making it last longer. Powerful enough to handle heavier cleansing tasks like washing pots, pans, dishes, cups, bake ware, food storage containers, yet gentle enough to wash vegetables and fruits. Dimensions: 4 x 2.5 x 2,5 in. This item is not dishwasher safe. Do not place it in the dishwasher.
