1. Remove the Silicone cover. Open the bottom cartridge filling port.
2. Inject directly into the chambered slot and closed filling port. Shake vigorously.
3. Put the filled cartridge into the Mi-pod body with the gold pins facing each other.

Included with each airflow card is two very small purple piece - these are airflow adjustment plugs. The Mi-Pod is designed to be able to both mouth-to-lung and direct-lung vape. However, if you want to make the airflow in your pods more restricted for a tighter draw, then simply insert the plug into the air intake hole (see image above). Make sure the plug is inserted with the air channel facing up like an upside down U and then push it in.
