Keep your reeds in a humidity controlled environment. This Hygro Case holds 6 of Bb / Eb or alto clarinet or soprano sax / alto sax reeds. It offers regulated humidification by air circulation and a hygrometry level controlled by a humidity indicator disc.
On the front of the case is a sensor which turns a different colour when the reeds have become too dry. From there, all you need to do is add water to the sponges provided.
