This is a list of frequently asked questions that may give you the answer to some of the questions you've been longing to ask.

  • What bottles do the concentrates come in?

  • Are your products good quality?

Our products are sourced directly from the manufacturers in USA, Italy, Poland and the UK. Our products are bottled in an sterile environment (ISO-7 Lab) so you can be assured you getting the same product as intended by the manufacturer.

  • Why do your concentrates have your own bottle and not the manufacturers bottle?

In order to keep costs down for the end user, we buy products in bulk and have them repackaged locally as it is too costly to import the original 15ml manufacturer bottle. However our 473ml size bottles are sold in the original manufacturer bottle.

  • What about your PG and VG?

Our VG and PG is sourced locally and both products conform to the international standard (USP/ BP Grade).

  • What is the expiry date on my product?

When it comes to the shelf-life of your liquid bases such as VG, PG, Nicotine and Flavour Concentrates, the length of time these products can be used is 12 months from date of purchase.

We get an 18 – 24-month shelf life from the manufacturer, therefore we advise 12 months from Date of purchase (as we rotate stock many times within this period).

The shelf life will depend on the correct storage conditions of the products mentioned above as the aromas in concentrates start to evaporate once the bottle is opened. Additives such as sweeteners and Nic start degrading once air is introduced into the bottle.

Recommended storage for PG, VG & Flavour Concentrates would be a cool, dark place that is out of direct sunlight.
Additives and Nic can also be stored in the Fridge (to pro-long the shelf-life).
Please also ensure all bottles are sealed when stored to prevent degradation.

  • Where do you store the products before I purchase it?

Our products are store in a sealed warehouse at room temperature with no sunlight so you can be assured it hasn't degraded in any way before reaching you.
