This is a fun gift idea for moms who love their coffee! The mug is heat activated with a different design showing depending on if the mug is full of hot coffee or empty.
If your mom isn't herself until she's had at least one cup of coffee, she might look something like the image on this mug when it is empty. The design is a black background with sleeping eyes and a snoring mouth.
When the mug is filled with hot coffee (or tea), the image changes (just like mom's mood when she's got coffee in her!). The background becomes white and the cartoon eyes open up!
This is a 12oz mug that does need a bit of special care to keep the image in good shape. Keep the mug out of bright sunshine for long periods of time, and for best results wash by hand. You'll get a set of two mugs with this purchase.
