I couldn't find the instruction manual even when searching for the product number online... The manufacturing year seems to be around 2005 (unconfirmed). National brand (manufactured by Matsushita Electric Industrial, made in Japan). I've descaled it several times, but is it due to aging? I think I've removed a lot, but the smell won't completely go away. It powers on, and the functions work. Therefore, I've rated the condition as the worst. Instead of drinking from it, how about using it for other purposes? Since I'm covering the anonymous shipping costs, I've set the price higher. I might lower the price, but I generally won't respond to comments, so thank you for your understanding. Thank you. ※This is a very old item, so I take no responsibility for it. Please contact current Panasonic for inquiries. #Matsushita Electric Industrial #National #National #Panasonic #Panasonic #Electric Kettle #Junk Item #Made in Japan
