Made of 304 stainless steel, the pods can be filled and swapped quickly. Five per package, includes storage tube. Great substitute for the aluminum dosing capsules that are more common for the Crafty/Mighty. These are stainless and have more mass so you'll likely have to increase temperature whixh could impact battery life snd even vapor production. They are not the aluminum capsules and they have different airflow so you should expect them to perform different.
