On top of the device is a removable plastic drip tip with O-ring seal to hold it in place and prevent leaks. You can replace it with any 510-style mouthpiece from your collection.
The main tank houses the central chimney and juice reservoir, enclosed in Pyrex glass. It can store up to 1.8ml of e-juice which should last around two days of average use. Since the glass exterior is part of the tank and cannot be disassembled, it can be quite challenging to wash and clean.
Aspire BVC configurations are wrapped with organic cotton wicks for premium flavors. Around the atomizer are four huge holes that draw the juice into the wicks and keep them well saturated. The top of the coil has a silicone stopper that works as spit-back protection while the bottom is threaded so you can easily replace it.
Around the base of the tank features four fixed air holes. Although you cannot adjust the size of the holes (like in higher end tanks), the draw is perfect for first-time vapers who are used to the sensation of pulling from a combustible cigarette.
