What is a drip-tip? A drip-tip is the small tip that is attached to your atomizer or clearomizer and is put in your mouth to suck the steam. There are two different sizes: 510 and 810. Most electronic cigarettes use the drip-tip 510 with a smaller diameter, in the mouth it looks more like the traditional cigarette. In reconstructibles DL atomizers or drippers will prefer the drip-tip 810 because they let pass much more volume of steam.
