Treat yourself and your best bong to a high end, quality glass downstem, handmade in in the USA by glass artist Alex K! Since the start of his glassblowing adventures in Alaska over 15 years ago, Alex K has been honing his craft and creating colorful glass art pieces for the smoking culture community. Now based in Minneapolis, Minnesota, Alex K makes a range of glass smoking accessories, from headie concentrate smoking sets to this clear borosilicate glass showerhead diffuser downstem, the ideal accessory when you want extra smoke cooling and percolation and don’t want to skimp on quality. This downtube features an inside-cut 18.8mm > 14.5mm glass-on-glass joint, allowing you to use 14.5mm slide bowls and bong attachments with an 18.8mm bong joint. Choose length when ordering, and remember to measure from the tip of your existing downstem to the top of the first joint when determining which length you’ll need to order for your spare or replacement downstem.
