This awesome-looking Hammer Carb Cap is made of durable borosilicate glass. It’s a dual-ended device that does double-duty. You can use the hollow handle & cap for airflow control and the other end as a dabber tool to apply your concentrate.
This Hammer Carb Cap works with thermal nails. When you cover your dab with this carb cap, you’ll be restricting airflow so your nail can retain heat longer. Your nail will essentially turn into a convection oven with hot air constantly circulating within the nail and cap. This allows you to maintain your ideal dabbing temp long enough to enjoy the full flavor of your concentrate.
