Here's an article I wrote about the trend towards 60ml and 120ml e-liquid bottles at brick-and-mortar retail shops. With sub-ohm tanks and high-wattage box-mods causing many vapers to consume e-liquid faster than ever, some e-liquid companies are dropping 15ml bottles in favor or larger sizes. There are even new e-liquid companies that only offer products in 60ml or 120ml. Some brick-and-mortar store owners prefer 15ml bottles for repeat visits, while others like what the larger sizes bring to the table. How about you? Do you prefer buying big bottles or small bottles of e-liquid you enjoy?
