Tupperware MM Square #2 Capacity 2.6L MM Square #3 Capacity 4L Seal color: Red #2 has some slight browning on the bottom. #3 has no noticeable stains or scratches. Personally, I think it's as good as new. Both seals close tightly and there is no odor transfer. Please refrain from purchasing if you are concerned about minor imperfections. Thank you.
