These beautiful olive oil bottles are super easy to use. Just fill them up with your favorite olive oil and place them on your kitchen counter or dining table to add a touch of color. They're dishwasher safe, so you can simply pop them in the dishwasher for a quick clean. Also, they're microwave safe, but when using them in the microwave, make sure there's no metal parts or foreign objects inside. For long - term use, avoid dropping them as they're made of terra cotta. If you notice any stains that the dishwasher can't remove, you can gently hand - wash them with a mild detergent.
