OC Bar disposable vapes are a good choice for both beginners and more experienced vapers looking for a low-maintenance, hassle-free device that they can slip right in their pocket. Each disposable comes prefilled with 2ml of nic salt e-liquid and will deliver up to 600 puffs, which is more than enough to outlast a pack of 20 cigarettes. Plus, the salt nicotine used ensures a smooth throat hit and quick craving satisfaction. Beyond that, inhale activation means that all you have to do is puff on the mouthpiece to vape.
