This 75-piece Frontier Logs™ set is great for the budding architect! One at a time, these logs can be stacked and interlocked to build anything a child dreams up. Your child will learn how to arrange logs to make simple or complicated structures. The easy to handle notched logs lock together for easy assembly and disassembly to provide hours of endless building possibilities. As always, these logs are stained with vegetable-based food coloring and sealed with paraffin wax, making them a safe, paint-free alternative for kids. Construction toys foster basic spatial relationship, coordination, visualization, and building skills. A great gift for kids ages 4 and up!
