The Humidifier hangs safely in the sound hole suspended by the instrument's strings so it never actually touches the body of the guitar. The Oasis OH-5 PLUS+ lets you see when your humidifier is ready for a refill. The Oasis OH-5 PLUS+ provides at least 50% more daily humidity output than the regular Oasis.
