This is a Nordic Ware Citrus Slice cake pan that looks like a fresh lemon wedge.  It was made in the USA.  It holds 5 cups of batter for baking a cake or possibly bread, or use it for a Jello mold.  It has a non-stick interior and is aluminum.  It is in good condition, though the pic shows some cake residue stuck on which I will remove before shipping.  Very cute pan!  Smoke-free.
