Thanks for your support!
Mugs are available in black or white. Sizes 11oz and 15oz.
The photo on the mug typically faces you while drinking if you're holding the mug in your right hand. (The cart preview is not accurate in the special case of mugs. Highly rectangular images appear to have added white space top and bottom when you choose "None" for cropping, but they will print correctly.)
Mugs are very durable and are microwave and dishwasher-safe.
