DIY
The DIY (Do It Yourself) allows you to create e-liquids for e-cigarettes in large quantities and at low cost, using a base, a concentrate and nicotine shots. It is important to follow a few rules for optimum safety:
- Do not vape a pure concentrate or a nicotine shot without first diluting it in a base.
- When handling nicotine shot, wear protective equipment (gloves, goggles).
-
Concentrates are laboratory-tested by the manufacturers to avoid the risk of molecules reacting with each other, so:
- Don't mix concentrates together, as you risk producing potentially toxic molecules by chemical reaction.
- Do not add additives to your preparations. Here too you risk creating various, possibly toxic, molecules. Calumette does not sell additives.
- Safe products: We offer only safe and controlled products, with a strong selection of brands.
