My boss told me to have a good day coffee mug - 11oz personalized mug. This is a custom coffee mug with the words "MY BOSS TOLD ME TO HAVE A GOOD DAY... SO I WENT HOME" printed and heat cured onto the mug. This mug is a standard 11 oz mug. This mug is microwave and dishwasher safe. This is a quality premium hard coated ceramic mug. The print is on one side of the mug only facing outward for a right handed person.
