30ml e-liquids are most commonly found as flavour concentrates. These e-liquid concentrates are used to make your own DIY vape juice at home, just add VG/PG and nicotine shots to create your perfect blend. If you are planning on making your own e-liquid, make sure you check out our mixing accessories. If you’re looking for larger bottles of ready-made e-liquid that can be vaped straight away - we recommend our range of shortfills.
