Using this coffee mug is easy. Just fill it with your favorite hot or cold beverage. When it comes to cleaning, you can safely put it in the dishwasher. If you want to heat your drink, it's also safe to use in the microwave. For long - term use, try to avoid dropping it as ceramic can break. Also, although it can handle dishwasher use, hand - washing gently every now and then can help keep its printed design looking fresh. Keep it away from extremely high temperatures outside of normal dishwasher and microwave use to prevent any damage to the mug or the graphics.
