DryKeeper is a dehumidifying sheet that absorbs moisture and prevents occurrence of inside-dew condensation for a long period, thereby suppressing rusting. It has the following features:

  1. It efficiently absorbs moisture and reduces atmospheric humidity, suppressing inside-dew condensation.
  2. It absorbs moisture in a high-humidity atmosphere and discharges moisture in a low-humidity atmosphere in a reversible manner. See Figure 1.
  3. Because of its reversibility, it can be used continuously for a long time.
