I bought thes sheets thinking they were manufactured in Pakistan, but realized too late that they were made in China. Not realizing they were from China, I opened the packaging and the sheets were emitting a very very strong odor. The odor continued even after washing. Now that I know they are from China, I know the explanation for the strong smell. It is from the use of formaldehyde and other strong chemicals that China is famous for using in their goods. Unfortunately for me, I have an allergic reaction when I am exposed to those chemicals, which means I can't use the sheets and can't return them either. I will also add that the sheets are scratchy and not soft at all. I think other buyers should be made aware of where the sheets are manufactured so this does not happen to someone else. It is too late for me, but hopefully this will keep another consumer from losing money and making the same mistake I did.
