El Jefe is a Spanish term meaning The Boss or The Chief.  It indicates that the holder is the one who is IN CHARGE. Sometimes it is used to describe the parent of a family.  This is a handmade ceramic travel mug created by me in my New Jersey studio. This is a stoneware mug measuring 6.25 in H x 3.5 in W x 3.5 in L with a black food grade plastic lid- a great eco friendly alternative to paper cups! Holds 16 oz. Dishwasher and microwave safe.
