Product Details

(From pyrexpassion.com) The mixing bowls are hard to find, indicating they were likely produced as a test item, special promotion, or limited edition set. Their exact date of production is unknown. The Mixing bowls did not appear in dealer catalogs and were likely produced a few years later based on their back stamps. Curiously, the three smaller bowls (401, 402, 403) have the newer, square PYREX micro-wave stamp on the bottom whereas the large 4 Qt bowl has the older, round stamp. The mixing bowls alternate solid rust (401, 403) and burnt orange (402, 404). The box for the mixing bowl set was unlabeled and unmarked, with the exception of a stamp that read "400 CRS." The "400" was in reference to the 400-Series Set (401, 402, 403, 404), but the significance of "CRS" is unclear.
