There are a few mass production humidor manufacturers that produce very good quality humidors. Prior to deciding which manufacturer to carry for
www.Cigarmony.com, I tested about 8 different mfgs, including Quality Importers.
Based on the humidor's seal, hardware used and the design and finish, I went with the Quality Importers humidors (5 years now). So far, I've only had 3 exchanged due to defects.
I hope this helps
