Stimulate your child's perception and senses with the Curioso discovery blocks. As your little one builds with these unique blocks, she'll discover some special surprises: two kaleidoscopes, special effect foil, a little bell, a mirror, a magnifying glass, a peephole, and another kaleidoscope made entirely of acrylic. The possibilities are endless: she can use the acrylic kaleidoscope as the beacon on a lighthouse, add the bell block to a train station, or interact with her own reflection in the foil mirror. With the exception of the acrylic kaleidoscope, the blocks are made of high-quality beech wood that from PEFC-certified sustainable forests in Germany. Their durable design will withstand years of play.
