You are purchasing a vintage Wilton 1987 cake pan of a Star.The pan number is 2105-2512. The pan would be great for Christmas, as a patriotic, or graduation.  The pan doesn't have an insert. Most instructions I believe can be found on the Wilton website. The pan measures 13 inches tall by 13 1/2 inches across by 2 inches deep. The pan doesn't appear to have any dents that would alter the baking of the cake. There are some light scratches to the outside of the cake pan. Still a nice addition to any cake pan collection. I currently have other cake pans up for sale. If you wish to buy more than one, I can combine them and give you a discount on the cake pans. Please just reply with an offer on each pan you are interested in.
