Using the Large Decor Walther Brownie Tray is a breeze. You can use it to serve brownies right out of the oven, or arrange small desserts like cookies and tarts on it. It's also handy for organizing things like jewelry or small office supplies in your home. When using it for food, make sure to place it on a stable surface to avoid spills. For cleaning, you can wash it with mild dish soap and warm water. Avoid using abrasive cleaners as they might scratch the surface. Store it in a dry place to keep it in good condition for years of use.
