All Ditanium Vaporizers Enails feature a titanium hand-piece with glass handle. The glass handle is frosted and is constructed with a standard 14mm female joint. It can be used alone when consuming liquids, or essential oils as they do not require a screen. The glass handle can also stay attached to the heater cover and does not have to be removed within 30 seconds like the titanium hand-piece. Also, the glass insulates the titanium hand-piece for user safety. This product is just the glass handle (titanium pictured is not included).
