We provide a 30-day money back guarantee on all of our products except for E-juice/liquid and cartridges/cartomizers. As E-juice and E-Liquid are not covered under our 30-day warranty, we suggest you buy small sizes first. Opened merchandise, products, and accessories can be returned within 30 days of delivery, but will be subject to a 10% restocking fee. You will be responsible for both the original shipping charges and return shipping charges. Opened returns must be in a sealable condition with original materials and packaging.
