For a multitude of reasons, just about any vaper can appreciate the convenience of disposable devices. The only hassle is having to buy them every few days after they die. Well, Duul has gone the extra mile and pre-filled these devices with 5mL of nic-salt e-liquid! This means the average lifespan is easily over 2000 puffs! Now you can enjoy all the convenience for around 3x as long before needing another! Combine that with the vast options in flavors and you have a winner!
