This collection features a range of MTL devices. Including well-known vape brands such as Aspire, this collection features only high-quality vape pens. MTL or Mouth to Lung devices are most common in vape starter kits or with an all day vape device. The action of mouth to lung is where the user first draws the vape into their mouth before they take it down with a second action. This mimics the action and feeling of smoking more closely than other more advanced vape devices. Perfect for those who are just starting out vaping or have recently quit smoking!
