62% Reed Humidifier Pack - Medium-term storage

This pack is perfect for when you open a box of reeds, but don't want to use all of them at once. Avoid having your reeds "get stale" by simply using this disposable 62% two-way humidity pack when you store them. Its two-way humidity control keeps your reeds at a constant 62% humidity, so your environment is too humid, it will will remove humidity, and if it's too dry, it'll add it back, automatically. Insane, right? Just put this pack, along with your unused reeds, in a heavyweight zipper bag and presto — you've got a humidity-controlled environment for up to 4 months! Comes in a sealed pouch for freshness. How does it work? Read on for the pseudo-science: 2-way humidity control works by continually responding and adjusting to ambient temperature and humidity by either adding or removing moisture to regulate a pre-determined Rh (relative humidity). The control device must change behavior as shifting conditions require. For instance, 2-way moisture control responds to shifting ambient conditions to provide only the right amount of moisture. There are numerous commercial products on the market that only provide 1-way control, meaning they'll give off moisture (humidifier) or absorb moisture (desiccant). Neither of them have the ability to regulate. A humidifier (sponge, gel, beads, crystals, silica, wet paper towels) all add moisture to a container, even if it's already too high. A desiccant removes all moisture. Those conditions are damaging unless you need very high humidity or none at all. These pouches are based on the scientific principle that certain salts mixed with water will naturally regulate a specific Rh. And there you have it. Your reeds don't care; they'll just be happy.
