I have several custom units from a west coast company called Adagio Custom Humidors. One has a 400 count capacity, all ventilated solid Spanish Cedar drawers, and automatic humidification that was built to match the style of furniture in the room it is placed. I also have a large unit for box storage that is solid Spanish Cedar, fully ventilated solid Spanish Cedar shelves, and automatic humidification that will hold 50+ boxes.
