The Armor universal silicone bowl and mouthpiece attachment is a unique smoking accessory that finds a way to fit in any smokers collection. The rigged universal male bowl joint fits both 14mm and 18mm female jointed water pipes. Remove the glass bowl and there is a groove for flat mouthpieces, and a circular insert for round mouthpieces to attach just about all 510 thread vape cartridges. This allows for safer sharing as a mouthpiece, AND allows you to use your favourite bong or dab rig with your cartridge vaporizer, giving you the smoothest hit from a pen possible!
