Thanks for the replies, but I've since learnt not to trust posted content as some similar products on Amazon also states stainless steel, only to have buyers crying foul that it was made of aluminum instead.
Kalidorif this is authentic then it is made of 18/10 stainless steel and is made in Italy. Unlike Bialetti Venus is made in China and Bialetti Kitty is made in India. But since Ilsa is a less popular brand I am gonna guess there is no knock-off, hopefully.
