Short-fill e-liquids are just like any other e-liquid, but they don't contain nicotine. Instead, they have space to add nicotine in the form of a nicotine shot, and this is where the name "short-fill" comes from; each bottle isn't filled to the brim.
UK vaping law states that nicotine-containing e-liquids cannot be sold in bottles larger than 10ml. Short-fills get around these laws, as the nicotine shots that you use with them are always 10ml.
Here at The Vaping Lodge we stock a wide range of short-fill e-liquids, with fruity, dessert, icy, tobacco, and many other unique flavours. All of the short-fill e-liquids on our website are 70% VG/30% PG. You can learn more about e-liquid mixes in our handy blog article.
