Not only the classic glass bong has dominated the cannabis lovers, our Freezable Glycerin Bubbler DAB Oil Rig is also popular in the market. Contrary to those low-quality bong in silicone, this Freezable Glycerin Bubbler DAB Oil Rig is made of high-quality Borosilicate glass material, which has excellent heat and impact resistance.
In fact, in addition to having high-quality materials, it is also equipped with a double-layer filtration system, built-in smoke filter and ice collector, which can effectively purify the smoke and provide a smoother smoking experience.
The unique design of the ice collector allows the addition of food-grade glycerin for cooling. The high viscosity of glycerin promotes heat exchange and cools the smoke to the optimal temperature.
