I need good quality of e-cigarette with lowest price. I can order 500 PCS for trial and then if your product good, I can increase the order to 1000 PCS/month. Specification: E cigarette pack (1 battery, 1 atomizer, 1 charger, 1 user manual, 5-7 PCS cartridge). Target price: $ 5.1- $ 5.3/sets. And for extra cartridge: $ 1- $ 1.3/pack (10 PCS). I hope you don`t have leaking cartridge (no leaking/swallowing). Also your product should soft sucking/inhale. Because I feel dissatisfy/bad experience when get sample from my supplier and their product leaking/swallowing. Only supplier that match with my requirement and target price that I like to cooperate! I hope you understand!
