Query: Corning = Quality

I bought this set as a gift for my bachelor brother so he'd quit using plastic items in the microwave. The sizes are perfect for one, and with the lids you can easily store any leftovers. The mugs are a good size, not small. And they're the good quality you expect from Corning products. He loves them and uses them everyday.
