Crisscrosses and double-unders are all good for the planet when they are done with the Green Toys Jump Rope. This eco-jumper is made with US-made 100% cotton rope (7 feet long and adjustable) and 100% recycled plastic handles. Little jumpers can burn energy and save energy at the same time. We use recycled milk containers as the main ingredient in creating our toys. Yes, the exact plastic milk jugs that you and your family drink from every day. Green Toys Inc. makes an awesome line of classic children’s toys constructed from recycled plastic and other environmentally friendly materials. This helps reduce fossil fuel use and reduce greenhouse gas emissions, improving the overall health and happiness of the planet.
