Keep your mandolin from drying out with this easy-to-use in-the-case humidifier. Similar to the Oasis OH-6 case humidifier, but shorter. It's wide at the top clip so it fits over the side of thickly padded cases. A small but strong magnet holds the humidifier to the clip. Humidifier can be easily removed for re-filling, and the clip allows flexibility for positioning in the case.
