The drying racks are wonderful, but from there should the Soap Bars be in cardboard, plastic, bins, open, or closed or what??? (until Soap Bars get into stores)
You can just push the soap together on a drying tray and then put a piece of liner paper or butcher paper over the tray. This holds the scent in better than spaced apart, yet lets the soap breath.
However, you can put them in cardboard boxes but make sure there is some breathing room on top and don’t line with plastic. In humid climates the soap can sweat, if too tightly enclosed. Plastic bins work but should be vented in humid climates.
If you are in a dry climate, you may find you can store in air tight containers or tightly packed in boxes.
