Nucleus' new line of food grade silicone products are something to pay attention to! The 10" Silicone Straight Tube Bong has the convenience of a silicone bong with the functionality of a glass one. With a melting point of over 1200˚F, you would really have to try to burn this bong. When you are done with your futile burning attempts, throw it in the dishwasher for a simple clean. The included 14mm male bowl and 2.5" 18mm to 14mm removable downstem slide right out when cleaning is needed. Choose between multiple color options.
