I want you to use it carefully because it is a business tool that you use every day Pit's products with such a feeling are professional products that customers themselves create high-strength and long-life products in a form that suits their usage environment. As a result of serious consideration of the work of using a dolly, we have made it possible to supply parts for Pit original products and realized a maintenance system that does not require customers to replace the dolly. Would you like to use a dolly that is safe, quiet, and does not damage the environment of our customers for maintenance, and aim for a society with less garbage together with us?
