Made from oiled olive wood, very hard and dense. It may have natural cracks that are due to the properties of the wood and do not represent defects. Olive wood has antibacterial properties, does not absorb odors or stains, and is resistant to acids and fats. Not dishwasher safe - it is recommended to wash by hand with a mild detergent and then dry with a cotton or microfiber cloth. To avoid cracks, occasionally apply olive oil or sunflower oil. Disclaimer: each item made from olive wood is unique, has different grain patterns, shades, and shapes, and may therefore differ from the image.
