PYREX Early American Cinderella Nesting Mixing Bowls 443 & 23 Vintage SET of 2 The PYREX Early American Cinderella Nesting Mixing Bowls 443 & 23 Vintage SET of 2 is a charming set of roundish, vintage mixing bowls crafted in America during the 1970s. The set includes two pieces. I obtain most merchandise from estate sales. I don’t know if the item has been in a pet free smoke free children free home once it gets to me. My sense of smell is terrible. Everything comes with a dryer sheet :) Please consider this when making purchasing. I do take returns - all you have to do is ask! :) I do not pay for return shipping though. Enjoy!
