Our Stacking Ring is a classic toy with a modern twist. Eight different rings can be stacked in various ways as toddlers explore color, shape, and size. The toddler-sized rings can be stacked right-side up or upside down and the rod is bendable at the base for added safety. Plan Toys is an incredible company with a dedication to environmental and social responsibility. This toy was made from PlanWood, an environmentally friendly initiative by Plan Toys in which reclaimed wood chips from the production process are used to create a high-density composite wood. Add a little organic colorant and Plan Toys has now created their most environmentally friendly toy line to date! And the best part? PlanWood is dishwasher-safe!
