Tupperware Stacking Ice Cube Trays ( mold numbers 1468-21 and 1468-22 )

Well, I must admit, I didn't know these existed!!! Approximate measurements 5 & 1/2 square I don't believe these were ever used but am listing as " good" condition as a precaution. no nicks or chips or stains. POSSIBLY discoloration of original product. As these are vintage, I have no way of comparison.
