Spa Vapes Shortfill E-Liquid. Since the introduction of TPD and subsequent TRPR regulations came into effect in May 2016, shortfill e-liquids have been the mainstay of sub-ohm vaping. Since that date, Spa Vapes has endeavoured to source the most interesting and highest quality shortfills around. We will only ever stock reputable brands. From manufacturers that comply to the highest standard of safety and testing. We are also proud to support independent UK manufacturers, not affiliated with Big Tobacco.
