The Helix small classic hand pipe from GRAV contains the mighty swirling helix function within a small and discreet hand pipe. The unique and widely shaped 5" venturi body design helps to cool and filter your smoke while ensuring your herb doesn't go to waste. Three air intake holes are integrated into the venturi body to add extra cooling and diffusion during hits, and the carb hole is located along the top of the bowl. Two roll stop feet are placed on either side of the bowl piece for extra stability and to protect against plant matter spills or breakage. This unique hand pipe does not require any water to work and is available at Aqua Lab Technologies today.
