A tough toy excavator for the sandbox is designed to withstand years of abuse. Heavy-duty bolted joints are used throughout, with no bearings or bushings to wear out. Our children believe that this Digger digs better than the others. The shovel is made of heavy metal, nearly 1/8″ thick. Because this is a larger and heavier digger, children aged 4 to 12 are recommended. It’s a foreign product.
