This is a very nice set of Pyrex primary colors mixing/nesting bowls. It is an earlier set from the 1940's, and all four bowls have the older T.M. Reg mark on them. They are not the later 400 series, but they are the same size and capacity as the newer sets. These bowls are in surprisingly good condition considering they are 70 plus years old. All four of the bowls have some scratches in the outside color glaze....some more than others. The worst is the la...rge yellow bowl. I took a picture of the worst scratches on it (see picture three). Even with these scratches, they still display very nicely. Please look at all the pictures, and feel free to ask any other questions you may have. Shipping is based on winning bidder's zip code. Payment through PayPal is due within three days of auction close. Thanks for looking, and happy bidding.
