The Uwell Caliburn G3 refillable pods are designed for use with the Uwell Caliburn G3 lite vape kit. They can hold up to 2ml of e-liquid and contain a built-in coil, which are designed for MTL (Mouth To Lung) and RDTL (Restricted Direct To Lung) vaping. When the built-in coil has burnt out, all you have to do is replace the entire pod, so no more fiddly coil changes.
 
The Caliburn G3 pods feature an easy top-filling design. To swap between an RDTL and MTL inhale, you can just switch between the 0.4 Ohm, 0.6 Ohm, 0.9 Ohm and 1.2 Ohm pods.
