All three of these Tupperware Modular Mate storage containers are in very good used condition.  The tallest, #1615, will hold 12 1/4 cups; the middle sized container, #1614, will hold 9 3/4 cups; and the #1613 will hold 7 1/4 cups.  The spots on the #1614 container (last photo), appear to be on the outside.  All the lids seal tightly onto the containers.

Please take a look at my other listings.  I have more Tupperware for sale, and I will combine shipping.
