Unusual Odor and Appearance in Nestle Nesquik Cereal

When I opened a box of Nestle Nesquik cereal that I had purchased from a supermarket chain a few hours ago, I was greeted by a musty odor. Even though the cereal had not yet reached its sell-by date, it had an odor that was off-putting and had an odd glossy appearance, as if it had been coated with something. I have been eating this cereal for years, but this particular box appeared oddly glossy as if it had been coated with something. It completely took me by surprise. I really hope that representatives from Nestle take note of this and address it.
