Brand new in box. Diameter of the steamer is 7 ¾” edge to edge at top. Bottom is 6". The height is approximately 3 1/2”. The handles are 10".
Also have this info from a fellow ebayer "I wanted to let you know that this steamer fit my forty-two year old 3 qt. RevereWare Saucepan perfectly."
NOTE: will ship with shipping label on the box..if you'd like the original box preserved, please send a note when ordering. Thanks :)
