Anyone recommend me good, high quality vaporizer supplier from Europe?
I think you are probably hoping for more than anyone can tell you without knowing your preferences in more detail. Many of the best items, especially in Europe, are all limited production, wait list sort of things that are ordered direct from manufacturer. Plus the TPD is wrecking all of them.
Most Europeans are going the China route.
This true, and don’t be surprised if your stuff comes through customs labeled “toy car” or “flashlight parts”
