Perfect for Hygrometer Calibration

I did not use this product for an aquarium, but it was very useful for calibrating a hygrometer in the range of 54% relative humidity. The total cost (including shipping) was very reasonable, and the product arrived well-packed in a sealed clear plastic bag. The product packaging is a tough black plastic zip lock bag that conveniently stores the product to maintain freshness.
