Disposables are pre-prepared devices, which are designed to be single use. They are currently available in 0mg, 10mg and 20mg nic strength. This page contains our collection of 20mg disposables. This is the highest strength available, and is designed for anyone smoking over a pack a day. Disposables are a great way for new vapers to experiment with different flavours and strengths, before committing to a complete kit. They are by far the simplest method of vaping, requiring no set up, and are available in a variety of flavours.
