An upgrade from the classic nesting toy, the extremely resilient and durable pieces in the Discovery Stackers sets enhance open-ended play indoors and outdoors. The heightened arch shapes encourage children 2 and up to explore relationships in balance and organic geometry. Available in a gradated, nature-inspired color scheme or vibrant rainbow colors, this arched set bridges the gaps between various play patterns and brings a new life to light play. Sets include 5 solid, arched pieces and double-sided inspiration cards complete with ideas for play, relevant vocabulary, and beautiful imagery. The tallest arch measures 6.9"L x 2.8"W x 5.3"H.
