Query: Wonderful Storage Set!

I got this Pyrex set as a Christmas gift for my folks to replace all those spaghetti stained tupperwares they've kept over the years. While the lids are a little difficult to get on and off at first, after putting them on a few times, they don't seem too hard to put on or remove. My guess is that I was trained to the tupperware lid indentations.The Pyrex bowls don't stain, don't leech plastics into your food, and the whole set looks simple and classy. Highly recommended.
