Bakers Edge continuous edge 9x12 brownie/cake pan. Pan has some slight marks from previous utensils. Underside, in narrow grooves, shows some white corrosion that wont affect baking. I reduced it somewhat with vinegar and scrubbing. Some fine steel wool might be whats neededor just ignore it!! Please see photos for all of the above and general condition. Feel free to message us with any questions. Thanks for looking!
