The Vaporesso EUC - Eco Universal Coil is an innovative performance atomizer created with affordability in mind. It is intuitive created, changing the way users typically replacement the atomizer coils. Instead of changing the entire coils, the EUC Replacement Coils only requires the changing of the core instead of the entire metal sleeve. The result is a more cost-effective design, while providing ample performance capability. There are two types of version, a Ceramic type that pays homage to the original cCell structures and a Traditional performance coil, with Kanthal, Nickel, or Stainless Steel heating elements.Compatibility:Attitude Tank - part of Attitude KitVeco Tank - part of Tarot Nano KitDrizzle TankEstoc TankVaporesso EUC Replacement Coil Features:Eco Universal Coil Design Innovative Replacement System - Changing of Cores instead of Sleeve0.4ohm Traditional EUC Clapton - rated for 40-50W0.5ohm Traditional EUC Clapton - rated for 35-40W0.5ohm Ceramic EUC SS316L - rated 25-35WJapanese Organic CottonVertical Coil OrientationAuxiliary Wicking SlotsIncludes:Pack of 10 EUC Cores Note: Does not include EUC SleeveThis product is for advanced user only!
