Ramps, cylinders, arches, and planks! It's easy to spend hours with this beautiful, hand-crafted wooden block set. It's visually stimulating with its naturally saturated rainbow hues. Varying shapes and sizes make it great for thinkers and builders, too. With cylinders and arches mixed in with triangles, flat rectangular planks, and basic squares, there's plenty here to keep even an expert builder at work. Comes in a solid wood storage tray; this can also function like a puzzle by neatly fitting the 63 pieces back in at the end of playing. Wooden Story is a green company indeed. They believe in creating safe toys for children to play and learn, made from nature. Children can smell the natural wood and beeswax and feel the organic texture of the wood, helping them connect with their senses as they explore and create. Hand-crafted in the Beskidy Mountains of Poland, they use only FSC-certified solid woods, helping to conserve natural resources. All pigments are eco-certified, non-toxic, and they are sanded smooth and finished with beeswax and natural botanical oils. They use paperboard packaging, great for storage or easily recyclable.
