Clay button humidifier
A tiny clay disk in a perforated metal case. Soak the button humidifier in water for 2-3 minutes, then place it in a container with tobacco to retain humidity for 5 days to a week. When it dries out, just resoak the humidifier for indefinite uses. We recommend keeping the button humidifier in contact with the air in your container for maximum humidification, so don't let it get buried in tobacco.
Ideal for 1-2 ounces of tobacco per humidifier.
