The Geek Bar S600 disposable vapes can deliver up to 600 puffs each which means they will last a bit longer than standard Geek Bars. A simple option each bar arrives prefilled with e-liquid and with a precharged battery, when empty just replace it with a new one. Available in either a 0mg, 10mg, or 20mg strength, you have the option of nicotine-free disposables or vapes that use nic salt for a smoother throat hit.
