Styrofoam plates and cups (Old Ottawa South)

for crafts, were not used but are old, 22 squarish 8 1/2 x 8 1/2 inch white Styrofoam plates and two 8 1/2 inch diameter white Styrofoam plates, maybe to make palettes for children's painting ? 28 regular Styrofoam cups (3 5/8 inch high) and 14 smaller size (3 3/8 inch high), cups are also white, all of these things were sitting around for a long, long time, so not for food use
