Smart IVG vapes are not refillable, as they use a closed pod system with prefilled e-liquid. Once the liquid is finished, the pod or device is replaced rather than refilled. This design is intended for convenience and ease of use, but it means users cannot add their own vape juice or reopen the pods. https://www.buyvapesbulk.co.uk/blogs/news/are-smart-ivg-vapes-refillable https://www.buyvapesbulk.co.uk/blogs/news/are-smart-ivg-vapes-refillable
