Aspire's new Cleito Shot Tank sports an overall diameter of 27mm. It has a food grade PCTG plastic construction, which is expected with any disposable tank design. At the top is where you'll see its wide bore drip tip, and at the bottom is where the airflow comes in. The airflow itself is non-adjustable, but provides a comfortable direct lung vaping experience. It does have a diamond design as well, so the airflow is quite smooth. The Cleito Shot Disposable Mesh Tank does have an e-liquid capacity of 4.3ml, and can be filled easily using the threaded top fill system.
