We have a solution to keep the little ones from their brothers' and sisters' smaller blocks. Jumbo plastic blocks! With these jumbo building blocks, you provide endless hours of play; playing is learning! The bigger blocks are easier to handle for smaller hands, and the choking hazard is much less. This educational toy will never be pushed to the back of the cupboard and will be a lifesaver when brothers and sisters want to play with their smaller blocks without interruptions.
