This is good quality 11 oz ceramic mug, heat pressed by me with the expression "Due to the confidentiality of my job - I don't what I'm doing " Printed on one side only. I can alter the wording and print with your choice, at no extra cost. If you wish me to make a mug specifically for you, please indicate the details at check out and/or email with your wording. I will do my best to oblige and will email to clarify your requirements. See my other listings for ideas! Or create your own!
