These blocks are like no other that we have seen. By stacking these blocks onto the baseboard and attached rods, boys will enjoy creating their own unique town. These blocks encourage boys to use their spatial reasoning, fine motor skills and creativity while connecting to the world around them. They can also be used without the base and rods to encourage more adventurous free play. The best thing about these blocks is that they are made from sustainable rubberwood, non toxic paints/dyes/lacquers and formaldehyde free glue.
