Please note that some tanks/clearomisers are made from polycarbonate which we feel is not suitable for some e-liquid flavours. Some flavours might affect the structural integrity causing it to graze or crack.
Please check that your tank is made from a suitable material that is not affected by flavours such as Aniseed or Citrus. We hope that all manufacturers will follow the trend towards Pyrex, glass and suitable plastics.
Our customer feedback is that our Bat Juice, Blackjack & Black Ice flavours may cause this reaction in plastic tanks, along with other manufacturers e-liquids.
If you would like any further information in regards to this matter, please feel free to e-mail us through our contact us page.
