I bought these because I got one of the Pyrex sets of storage dishes that came with four different sizes - and that set had three each of the other three sizes and only one of these. It really bothered me.... haha. Also tho, I use the bigger ones just as often, so I wanted a couple more of them. They were wrapped super well, individually covered in Bubble Cushion, so arrived in great condition. Really glad to have a well-rounded set now ;) Thanks!
