I have been using these in my panty for a few year, and some are stacked. I have had a couple lids break before, but had concluded that was due to a certain offspring using them to stand on -(dog food bucket...)- so, I replaced.
Now, I just noticed my bottom hard red wheat bucket has a broken lid, I dont know for how long. No one climbed on or did anything to them. But, This is a stack 3 buckets tall, and they are filled with red winter wheat, so they are heavy, and it is the bottom bucket lid that is broken.
Anyone have isue with lids breaking ? Maybe I overstressed by putting 2 buckets on top ? I will also see if I can ge ahold of Gamma Company, I had not seen anything about not stacking them
