The Green Toys Stacker takes a classic toy and makes it safer and more playful. The eight whimsically colored nesting pieces stack easily from large to small, while also allowing little builders to use their imagination and stack in any order. Little ones can develop hand-eye coordination and color recognition while having plenty of Good Green Fun. Most importantly, the Green Toys Stacker is safe. Its unique design has no center post. Here’s an even greater incentive to make your kids drink their milk. Green Toys uses recycled milk containers as the main ingredient to create their toys. The milk containers are re-processed into high-density polyethylene (HDPE). It’s one of the safest, cleanest plastics around. Everything from the collection of materials to the production of Green Toys occurs in Los Angeles, CA. Local production of toys means that far fewer miles are used for transportation. On average, every pound of recycled milk jugs used in the making of Green Toys saves energy equal to 3,000 AAA batteries. Green Toys products are tested by nationally recognized, independent, third-party labs (located in the USA.) They contain no traceable amounts of Phthalates or BPA. They are also designed without any external coatings, eliminating the fear of lead paint. Although Green Toys may not be as nutritious as a glass of milk, you no longer need to worry about what odd chemicals your kids are ingesting every time they launch a playful bite into one of their toys. No BPA, PVC, phthalates, or external coatings. This Stacker is made in the USA from 100% recycled plastic milk containers which save energy and reduce greenhouse gas emissions. Dimensions 7-3/8” H. Extra Safe with no center post, color combinations may vary.
