Have this teapot bought at a market place traders (The Coffee and Tea Company / My-own-coffee de) and have a cheap copy sent get of inferior quality. Had then the original ordered directly from Amazon.com (for 30 euros instead of 17 euros), and then of course get sent the original.
Do not want to know what cheap materials used in the reconstruction. Since foods are zurbereitet with this product, the use of poor health but plastic is questionable. I do not want to take the risk in any case.
So rather pay a little more, but get high-quality goods.
