The “Core Series” Resin 1.0ml Cartridges are designed to deliver the best experience with both thicker and thinner oils. With the added strength of a resin body and the durable polycarbonate tank, the appeal is apparent right away to producers and consumers alike. Being constructed from high quality resin, these cartridges are lead-free as well as leak-free. Our resin cartridges are tamper proof and a non-refillable vape cartridge option. Being as they are sealed, they do require an arbor press or mechanical device made to seal cartridges permanently. Core Series Resin cartridges use a universal 510-thread base that pairs well with any compatible battery. Available in two sizes, 0.5ml and 1.0ml, these resin cartridges offer the consumer more choices for their vaping experience. Also included is a base mouthpiece with a clear plastic round shape.
