Query: Disappointing

Bormioli Rocco Frigoverre Round 4 Piece Storage Set with Frosted LidsThese storage containers are attractive and glass is the current recommendation for use in a microwave, which is why I purchased them. A major drawback is that the lids are NOT microwavable. I would not have purchased them had I been aware of that fact. Unfortunately, you have to read the fine print to discover this particular inconvenience. They are heavy to carry to work for lunch and you have to push the center of the lid down carefully and firmly or the contents will spill.
