This high quality ceramic tea or coffee mug is dishwasher and microwave safe. You can wash and re-wash without worrying about fading! All my mugs come with a 30-DAY MONEY-BACK GUARANTEE. I stand by my mugs 100%. I continually update my inventory with fresh designs. So don't wait to order yours! Have any questions? Just send me a message. I'll get back to you asap. I am happy to take special requests and do personalized orders. My mugs come printed double-sided with the standard design by default, but that if you choose personalization, I will replace one side with the personalized text.
