Anti-corrosion possible 6 to 12 months quality retention: unopened 3 years received what was manufactured 6 months ago. The expiration date is too short. The packaging of the goods themselves was just wrapped in paper .... If packed in a sealable plastic bag, you can use it with confidence.
Product that was manufactured ten months ago from the date of receipt arrived even though the expiration date in the unopened state is indicated as 3 years from the date of manufacture. Although it may be a good product, I feel very damaged.
