A lovely set of stackers that are made from recycled milk jugs, contain no BPA, Phthaltes or pvc, and if you want to feel even better the product is made in the USA. This is a great toy to explore with your older baby or toddler.  While you can stack them in "order", you don't have to- a nice feature.  Each cup has two small holes for safety purposes - so that your child can not create a suction over his face.  Even with the holes this is a fun set to bring into the bathtub.
