Crown7 is in fact, a leader in the electronic cigarette industry. We started in 2007 and others simply do not have our experience and knowledge of the industry. Crown7 has traveled to extensively to over 10 different manufacturers over the years and we assure you that we offer the best products to our customers, bar none. Customer service is our foundation and our commitment to our customers. If you have any questions, comments or concerns, please call or email and we will promptly respond.
