Fuel up for a long night of observing with a hot beverage, and the constellations of the night sky will reveal themselves to you - literally! Mug design includes 11 northern circumpolar and zodiacal constellations including favorites like Orion and the Ursa Major/Minor along with possibly less familiar figures like Perseus and Hercules. When the mug is filled with hot liquid, constellation names and images become visible.
Mug holds 12 ounces, or 350mL if you're feeling metric. Microwave safe, but not dishwasher safe.
