Hi all, hope you're doing well.

Here's a potentially useful info from Slovenia. A manufacturer of 100%
cellulose napkins ("serviette"), usually sold to restaurants & hotels
at cents a piece, tested & certified them for personal protection with
the national University Clinical hospital. I suppose you might have
local versions of this available everywhere.

Here are some links, partially in Slovenian.
