@DasSauerkraut @coolboymew not just any plastic but polytetrafluoroethylene (PTFE).

You can also find them in ceramic (I think porcelain) or borosilicate glass.

They also come in multiple shapes and sizes. Octagons, with pivots, without pivots, hexagons, cylinders, etc.

Reject the globohomo agenda and stop using plastic when you don't have to.
