TFV8 Baby EU Core Coils come packaged with SMOK products like the Procolor, T-Priv, GX2/4 and OSUB King 220 starter kits. Designed for the UK and EU market, these coils are compatible with the TPD compliant version of the Big Baby (EU Edition) tank. The EU Core Baby coils feature a fatter Stainless Steel barrel which reduces the tank capacity to 2ml. The coils also have a different top screw arrangement. This is designed to connect to the shorter chimney sections found in the EU Edition Big Baby tanks.
