I don't know but they don't write "Toothpick" on the side of them.
When we did make them, they were made of Birch. Have no idea what kind of wood the Chicoms use to make them now.
I remember the old Looney Tunes Cartoon where they shaved down on whole Tree to make one toothpick. Nowadays, the same cartoon would be banished from Network TV so Al Gore wouldn’t have a Coronary.
