In order to provide savings for our customers and get the same value, portions of our humidor interior are made of cedar wood. Once the humidor is closed everything inside is sealed. The cedar smell will remain in the box giving positive effect on the flavor of your cigars. Therefore there is no need to make the inside of the humidor completely of cedar. If you research cigar humidors, there is no 100% cedar humidor. All manufacturers use the same method to make their humidors. The reason our prices are much better than other sellers is because we have our own manufacturer and make our own products. We also sell our humidors to few of biggest retail chain stores in United States and Europe. That's why we get good items at lower prices. We do not buy our products from other middle men and we pass the saving on to our customers. We hope this helps and please feel free to email us with any other questions or concerns that you may have. ** Maximum capacity subject to size of cigars stored.
