Glass Reducer Stem Diffused

The glass reducer downstem is crafted from high-quality borosilicate glass, renowned for its durability and heat resistance. Featuring six precisely cut slits, this diffused downstem ensures optimal filtration and diffusion of smoke. Designed to seamlessly convert an 18mm ground joint to a 14mm joint, it effectively reduces the length of glass protruding from your bong, resulting in a more aesthetically pleasing appearance. Slit diffusers are widely recognised as the preferred choice for diffused stems, offering an exceptional smoking experience characterised by smooth and flavourful draws.
