Plastic foam (for lg. pot filler?) (W section, Bowie)

These pieces of plastic foam were used as packing material. They are plastic, not as light weight as styrofoam (but still lightweight). I cut them up in case anyone needs to fill the bottom of a large planter (to cut down on the amount of soil needed, reduce the weight), or has some other use for them. The stack shown is roughly 11" x 11" x 10".
