The Uwell Caliburn G Empty Cartridge is a refillable 2 mL pod designed for Uwell’s Caliburn G (and compatible devices). Made of durable PCTG food‑grade plastic, it features a top‑fill port hidden beneath the mouthpiece cap for mess‑free refills. It also includes a dual airflow system (by rotating the cartridge 180°) to allow both MTL and restricted DTL vaping styles. The cartridge accepts Uwell’s Caliburn G coil series via a press‑fit mechanism and includes a silicone check valve to reduce leaks.
