Our Capella flavorings are broken down to 120mls for customers looking to make their own e-liquid. You can add as little or as much flavoring as you'd like or any number of combination of flavors. Most flavorings are best used between 10-20% ratio. The more flavoring you add the stronger the flavor will be. If you have any questions about making your own e-liquid feel free to stop in or give us a call and we can assist you in the process.
