The OBS Oner Vape Kit is powered by a single 18650 battery (Not Included), and despite being discreet in size, it packs a great deal of power, along with featuring comfortable and sleek aesthetics. The refillable pod is made in PCTG, making the e-liquid present inside it highly visible, which allows you to easily detect when your vape requires a refill! The translucent pod not only is very easy to use, but it also features an accurate airflow adjustment, providing a great deal of customisation in your vaping experience.
