Doughnut-shaped nonwoven fabric soaked with harmful smell chemicals. It was wrapped in gold color wrapper.

It's white, and made of cotton. (nonwoven fabric) It's sealed in a gold wrapper. (same material as a small cosmetic sample) No words were written on anywhere.

The size and thickness is as shown in the picture.

It's wet and smells bad. (a strong smell of chemicals) The finger that touched it stings.

I got this delivered from AliExpress. I never ordered this. It is not included as a component among the items I ordered. The site responded that they don't even know what it was either.
