This is a really heavy set. The 3 part mold is pretty unusual and difficult to find. Please be sure to look at all of the pictures to show each part. The two sides and a hat looking part that sits inside to give it an opening. I paid much more for this set than what I'm selling it for. I believe it is a German mold but am unsure. The only marking I could find is number 570 on it. It measures 5.5" not including the hinge. I think when you put in your chocolate, paper mache or whatever you are using, you may need to put rubber bands around it. I don't know if pewter is food safe. Please be sure to find out before using this for chocolate.
