Thank you for shearing!
FYI: that teabag is nylon or PET - plastic basically. Some people like it as it does not have the paper taste.
However, a Canadian study from 2019 revealed that it’s up to 16 microgram of plastic (14 Billion micro- and nanoparticles of plastic) per tea bag, which you take up.
I know it’s fancy and a beautiful invention. But not very healthy, I am afraid. Neither for you nor the environment.
