Believe it or not, the drip tip (mouthpiece) featured on your beloved vape tank is not only giving a unique touch to the overall look of your ecig, but plays an important part of your vape experience. Combined with the vaping technique you feel the most comfortable with, either mouth to lung vape or direct lung inhale, the drip tip plays a big part in giving you the best throat hit or the consistent clouds of vapours you plan to have. The long, narrow drip tip type is by far more appropriate for the mouth to lung vapers, as the direct lung fans will be more into the wide drip tip models. Either you want to go for the Pyrex glass drip tips, or the ones made of stainless steel, here is the place to find the best selection of drip tip compatible with most of the sub-ohm tanks on the market.
