A truly classic design and one of our best sellers since its introduction in 2008.  Black and gold with scallop shells that make a great presentation with the Black Compass pieces. 

Rocks glasses can be microwaved for up to 1 minute.  After making coffee allow at least two minutes before pouring coffee into the mug.  Putting a metal spoon in the mug when pouring the hot liquid is recommended.   Rocks do not have a non-skid feature.
