Mugs are available in black or white.

The photo on the mug faces you while drinking if you're holding the mug in your right hand. The photo can be wider than it is tall; wider photos wrap further around the mug.

The minimum pixel count of the mugs is 450x1275 for 11-ounce mugs and 525x1275 for 15-ounce. If you submit an image that size and choose the no-crop option in the shopping cart, your entire image will be printed.

(The no-crop preview in the cart is not quite accurate in the special case of mugs. Highly rectangular images appear to have added white space top and bottom, but they will print correctly.)

Color reproduction on mugs is not as accurate as on photographic prints.

Mugs are very durable and dishwashwer-safe.
