The DryMistat fits easily into any humidor or storage container. It's two-way humidification system maintains 70% relative humidity at all times. This keeps cigars in perfect storing & aging condition. The humidifiers are absolutely leak proof.
How it works: space age plastic tubes allow humidity to escape through micro pores while holding water inside. The crystals will shrink slowly as water evaporates over time. Simply refill the tube with Plain or Distilled water to recharge them.
