The Cooling Freeze Travel Cup Bubbler measures 6 inches tall and fits perfectly in the cup holder in your car or truck. This stealthy and functional bubbler has a freezable cup body to help cool smoke quickly and allow for larger hits. The cup also has the appearance of crushed ice to dissuade any lookie-loos. The bubbler also features a silicone top with a straw style mouthpiece, and it includes a 14mm male herb slide with a handle and a cap to prevent leakage. Colors vary.
