This is a vintage Pyrex Corning Ware Casserole Dish Blue Cornflower 60 min Kitchen Timer. These timers are rare and are a great addition to a Pyrex collection. This one has a white plastic body that has not turned yellow like some of these you will see, and it's clean and the timer works. The one issue is a cracked piece in the knob on the lid that was repaired with clear epoxy (see photo), so it's sold as-is. Please review all of the photos, as they are part of the description, and will help you best judge the condition. Also, feel free to ask any additional questions you may have before purchasing.
