Frieling
Genuinely designs plastic out of the French press, a product where the plunger, lid, and filter frame are almost always plastic. The double-wall 18/10 body, lid, plunger, and dual mesh filter are all stainless, so nothing in the brew path is plastic or glass. This is a real plastic-free design, not marketing around a plastic core.
How clear are their specs?
Names the 18/10 stainless construction and the all-metal brew path plainly; the materials are simple and visible with no coatings or hidden liners to disclose.
