Swirl UV Worked Bubble Carb Cap

This cool 29mm carb cap made of sturdy boro glass has a worked glass bubble in the center that reacts to UV light.  Use the carb cap under a black light and get all spaced out! It's a trippy color-changing carb cap that will put you in touch with your hippie side. 

The swirl UV worked bubble carb cap works with both banger and thermal nails.  Not only does a black light make this carb cap glow, but you can also manipulate the carb cap to get the most out of your dab sessions.  The carb cap will allow you to dab at lower temperatures for better flavor and ensure all your dab is vaporized with no waste left in your nail.
