This is a mug shaped like a Tiki with a porthole on the reverse that you can see through. A large anchor design on the reverse also. Glaze is a sort of blue rutile with brown and white coloring as well. Thanks to a removable clear inner chimney glass and a flashing LED cube, this mug allows you to view and illuminate your drink of choice. The ceramic outer mug measures approximately 7.5" tall and the inner plastic mug approximately 6.5".
