The Uwell Caliburn G3 pods feature a 2ml capacity and a convenient side-fill design. Whether you're at home or on the go, refilling your pods is a breeze. To switch between RDTL (Restricted Direct-to-Lung) and MTL (Mouth-to-Lung) vaping styles, simply swap between the 0.6 Ohm and 0.9 Ohm pods. The Pods feature a fixed coil so once the pod is burnt out just replace it with a new one. This makes vaping convenient and easy to manage.
