Tupperware canister set

Two clear Tupperware canisters with orange rim and lid. Normal wear from being used over the years but still solid. Both size 13 1/2 cups. The toaster cover, apron, pot holder and oven mit seem to have never been used but stored. I posted a picture of of the inside of the toaster cover and there’s a little brown spots that might be able to wash out. I didn’t want to wash it and take away from the stiffness.
