Bar salts are a type of e-liquid which is designed to be similar to those found in disposable vapes. They are available in all of the most popular disposable vape flavours and utilise nic salts for the same smooth inhale.
In the case of ELFLIQ, they are actually the same formula of e-liquid which is found in the Elf Bar disposable vape range. Many vapers choose to use a bar salt vape juice if they have previously enjoyed using disposable vapes, and want a similar vaping experience but in a refillable vape kit. This is because using a refillable vape with a bar salt vape juice can save you money in the long run compared to continuing to use disposable vapes, and also produces far less waste.
