8 Plastic corner supports (or something else!) that were used to support foam corners on a recently disassembled bed. Certainly you have some creative use for them! Halloween is coming up. 4.5" High x 6.5" Wide x 6.5" Deep. Note in the pictures that they are not a completely square shape -- one part curves in. Easy porch pick-up in Amherst just south of UMass.
