This is an electric water boiler/pot from Peacock. I'm selling it because I found it while cleaning. It's a new, unused item (the instruction manual is a bit worn). Although it's new and unused, please refrain from purchasing if you are sensitive to items that have been stored for a long time. Model number: WMP-220 Capacity: 2.2L Manufactured in 1997 The rattling sound when you shake the product is the sound of the valve that minimizes water leakage if it tips over. This is not a malfunction. Please understand that this item has been stored at home before purchasing. Electric pot, Peacock
