The Vaporesso EUC Universal Coils are designed to be cross compatible with any EUC tanks including the Vaporesso Veco Tank (which is also part of the Tarot Nano Kit)
Instead of replacing the whole coil head, with the EUC Universal coils, only the (fully organic cotton) core wick is replaced each time keeping the metal outer sleeve. This is far more cost effective and the drop in design is super simple.
