BOSS Titanium believes that their new Mul-Ti Carb Cap is the last carb cap you'll ever need to own. It's specifically designed to work perfectly with a variety of titanium, quartz, and ceramic domeless nails. It's also meant to great with quartz bangers too. It's call the Mul-Ti because the dabber can be screwed into 3 separate places on the carb cap in order to work efficiently with the style of nail you're using. This is truly an awesome carb cap that will become a daily workhorse that'll last you a lifetime.
