Using this personalized coffee mug is easy. Just fill it up with your favorite hot or cold beverage. It's dishwasher - safe, so you can simply pop it in the dishwasher for a quick clean. Since it's also microwave - safe, you can reheat your drink without any worries. However, to keep the mug looking its best, try to avoid using abrasive sponges that could scratch the surface. If you're hand - washing, use a gentle dish soap and a soft sponge. This mug is printed in the USA with copyrighted artwork, so treat it with care to maintain its unique design.
