Wake up bright eyed in the morning with a large mug of joe. Hand painted coffee mugs designed to look like a close up of an owl. Each is approximately 4 inches tall and comfortably holds 12 oz. of your favorite hot or cold beverage. These mugs are painted with heat set acrylic enamel and are supposedly dishwasher safe in the top-rack, however for longest life hand washing with warm soapy water and soft sponge is highly recommended; but DO NOT use any abrasive cleaners or abrasive sponges.
