About this Product

Product SKU: HBK-KED1-19-BL-10CM

This 18.8mm Glasscity Slitted Diffuser Downstem offers powerful diffusion for an unbeatable price.

The slits in the diffuser divide the smoke and produce lots of fun bubbles. By the time the smoke reaches your lips, it will be cooled significantly for a much smooth rip. This slitted diffuser downstem fits 18.8mm ground joints and is available in numerous lengths and colors.  Pick the color and length you need and claim yours today.
