Note: I do not know if these test results apply to all years of manufacture of this toy. The toy is not marked with the years of manufacture and there is no clue (from the markings) as to the year of manufacture. HOWEVER: the colors are distinctly different than the colors of vintage Tupperware plastic I have tested that have been positive for Lead, Mercury, Cadmium and Arsenic. If you have more information about this product (like the range of years of manufacture for this particular toy in these colors) please do comment below so other readers can benefit from that info. Thank you!

For 40 + years kids have played with the Tupperware shape sorter an octagon shaped ball with holes cut for blocks of different shapes. I bought new sets for my grandkids in 2014, they still play with them daily. The colours look like your blocks. The ball is red and blue, the blocks are yellow. Tupperware has a lifetime warranty on their products if a seal cracks under normal use they replace it with a similar item or the same item for shipping costs. Is all Tupperware bad?
