Staub 22cm White + Vintage Knob This is likely a cocotte with a copper knob, sold at a department store in the US or somewhere else about 3-4 years ago. The copper knob has been removed and replaced with a vintage knob. White was a very rare color at the time, so I displayed it on my kitchen shelf for about a year. After that, I stored it wrapped in bubble wrap. Please note that some stains remain. Vintage knobs are also expensive, so please refrain from price negotiations. I threw away the box. I preferred the vintage knob over the normal knob for the white color, but if you don't like it, feel free to change it to your favorite knob and enjoy!
