Question
Are the ceramic mugs printed on one side or both sides?
Answer
Coffee mugs are printed on two sides by default, the same image on the front and on the back (unless you've uploaded two different images for the front & back prints.
(If you want a different image on the front of the mug than the back of the mug, upload the 2nd image in the Print Location 2.)
If you want something different, be sure to communicate that to ICON ECOM with your order.
