The Oasis Case Plus+ Humidifier uses the same evaporative membrane as the Oasis Plus+ Humidifier, providing 50% more daily humidity than the Oasis Case Humidifier.

This humidifier is designed for use in drier environments where the relative humidity is below 25%. The Oasis Case Plus+ humidifier, like the Oasis Case Humidifier, uses a small but powerful magnet, embedded in the humidifier's seam, to attach to either a small sticky-backed piece of stainless steel or a metal clip (both are provided with the humidifier).

The Oasis Case Plus+ Humidifier can be used in stringed instrument cases such as violin, viola cello, guitar, or mandolin.

The case-style humidifiers attach to the inside of your instrument case. They give you the same reliability and ease of use as our original humidifiers, outperforming other case and instrument humidifiers by doing the following:

• Making it easy to see when it's time to refill.
• Providing long-lasting humidification.
• Ensuring no leakage due to overfilling.
• Promising two levels of leak protection.

Recommended for 25% or lower humidity.
