This is a simple 3D model of an old vintage key. The key has a classic decorative shape at the top and looks like it is made of worn brass or old metal. I tried to capture the slightly used surface and small imperfections to make it feel more realistic. This type of key could be used for old doors, chests, or antique locks. It can work well as a small prop in games, scenes with historical or fantasy themes, or as a decorative object.
