Being a natural product, each bowl is unique in shape but they are typically approximately 13cm in diameter and 6cm high. Each design motif comes in a variety of colors to suit every decorative environment in a home or office. Whilst the coconut bowls themselves are quite strong, we do not suggest that they are placed in the dishwasher. Simply hand-wash and dry them after use.
