Ejuices come in all shapes and sizes such as a 30mL bottle depending on the respective manufacturer and their marketing strategies. During the infancy of the vape industry, the most common bottle sizes were 15ml bottles. As the industry matured, vapers demanded bigger bottle sizes with more affordable pricing. Soon thereafter, manufacturers such as Cuttwood and Beard offered their best flavors in 30ml, 60ml, and 120ml options while gradually phasing out 15mls. More recently, many newer brands such as Air Factory, Jam Monster Liquids, and Kilo Sour Series have shifted toward Chubby Gorilla bottles with bottle sizes ranging from 60ml to 120ml sizes. Chubby Gorilla bottles also give users an added layer of usability since they are in the shape of a unicorn bottle and are not as rigid as glass bottles. As the industry continues to evolve, the trend of larger bottle sizes with a reduced price per ml seems to be standing the test of time.
