The Smyle Pen is designed to last longer than other disposable vape pens on the market. Our pen is capable of holding 1.5 grams of oil, which is significantly more than the standard amount found in other disposable pens. This means our customers can enjoy a longer-lasting and more satisfying vaping experience with a Smyle pen. However, the actual duration of the pen will depend on your usage habits and inhalation techniques.
