This cast aluminum muffin pan is by Nordic Ware.  It is for making maple leaf shaped muffins.  It is still wrapped with the original cardboard sleeve that has a couple of recipes on the back. The sleeve does have some wear along the edges. It measures approximately 9 3/4 inches across and 1 1/2 inches deep. Each muffin hole measures approximately 2 3/4 inches by 2 1/2 inches and 1 1/4 inches deep.  According to the cardboard sleeve it has a 2.1 cup capacity that I assume is for each muffin.  It should be hand washed as needed.  When properly packaged it will ship at a 3 pound rate.
