I love my Pyrex mixing bowls. They are 3 sizes and sit inside one another to save space. I have had my set for years and I still have them all. They are tough glass and have held up to being banged around. They are not scratched or cracked either. I like having these because I can use the size I need rather then using a huge bowl for a small amount. I definitely recommend them to anyone. I like the brand and the price is fair. You can get Pyrex at kmart or Wal-Mart.
