blu e-cigarettes have two primary elements: the device (that contains the battery) and a container for the e-liquid, which is either a Liquidpod or tank. The device can be recharged, and the Liquidpod or tank should be replaced when it no longer produces vapor. The blu disposable has an integrated design that contains both but is only intended for one-time use.

E-liquid used in blu products is made in the USA with domestic and imported ingredients. A listing of e-liquid ingredients and nicotine levels can be located on blu product packaging.
