Weed Star - 7mm Glass Precooler with Diffuser Downstem
Add extra smoke diffusion and keep ash out of your bong water with this 7mm-thick glass precooler from Weed Star! The removable slitted diffuser downstem breaks up smoke into smaller bubbles, filtering your hit for a cooler and smoother pull before it even reaches the main chamber of your water pipe! Weed Star's "WS" logo is featured on the bottom of the piece in black, with the classic blue Weed Star logo applied along the downstem. This precooler fits into any bong with an 18.8mm glass-on-glass joint, and the 18.8mm joint on the top comes equipped with the 18.8mm > 18.8mm diffuser downstem and a 18.8mm slide bowl.
