A30G0909 VCI Paper Prevents Rust, Corrosion On Ferrous and Non-Ferrous Metal, 9" X 9" Sheet, Blue (Pack of 1000)

Great product and right size. Slip 1 sheet into a half gallon, ziplock bag with small to midsize (~2lb) metal part. For longer metal parts, ~40" & ~10lbs, use three sheets and garden size Heftys. (Do not need to worry about sheet contacting the metal part, like one would with a saturated dessicant bag.) If I understand the product correctly, the sheet should be put into use within a year of the date it was manufactured. Product I received was less than two months post production. I plan to do some long term, in ground testing of bare-steel tubes to determine effectiveness of this product before storing more expensive parts in a better environment.
