The Geo Knight Digital Combo Full-Wrap Mug Attachment is an interchangeable attachment compatible only with the Geo Knight Digital Combo Heat Presses. (Heat press not included) The full wrap mug attachment for the DC16 and DC16AP uses the same exact super-robust heater band & pressure adjustment as the DK3 model Geo Knight heat press. All standard cylindrical sublimatable items can be pressed on the Full Wrap Mug Attachment as are done on the DK3. The Digital Combo press controls the temperature and serves as a timer for this instant plug-in attachment.
