Disposables contain e-liquid that’s tested to TPD standards and are legal to sell in the UK. Disposables are just as safe as other e-liquid that you would use to fill up your tank. Anything sold here at Prime Vapes has been tested against these regulations and is safe to sell here in the UK. A disposable may become unsafe when it’s not purchased from a reputable company. This can include unregulated e-liquid, like fakes or replicas, or a tank that’s bigger than 2ml.
