What Is The Difference Between E-Liquid And Shortfill?

In the UK, the maximum volume of E Liquid that you can buy in a single bottle if the e liquid contains nicotine is 10ml. Nicotine-free e liquid is not subject to such restrictions and so can be sold in larger volumes. Shortfills are bottles that are underfilled with nicotine-free e liquid to leave room to add nicotine shots. For instance, a 60ml shortfill will contain 50ml of e liquid and room to add one 10ml nicotine shot. Shortfill is merely a term for a container that holds e liquid.
