Inexplicably, I found a bottle of Roundup, unused and still in the Home
Depot bag, tucked away in one of my suitcases in the basement. I don't
remember buying it, but I guess I did.

The only thing I can think is that a housekeeper we had a couple of years
ago stuck it in there when she was cleaning and probably forgot it. But who
knows...

Since it had not apparently leaked, and was unused, is it ok to use the
suitcase?
