Bests & Worsts Reviews from Amazon

The product description is not very detailed, so I will provide some additional information. The canister is perforated steel, round, and measures 4 inches high by 5 1/4 inches in diameter. The bottom of the canister is labeled "Hydrosorbent Silica Gel Dehumidifier 750 Grams Silica Gel", "protects 57 cubic feet / 1614 litres", and contains the reactivating instructions (325 F for at least 3 hours). Note that it ships in it's own packaging, which is a rather thin cardboard box. Select "this will be a gift" during checkout and it will ship inside another box with padding. I hope you find this additional information helpful.
