Hario Skerton Plus
Ceramic burrs and a glass catch bowl, but the hopper and upper body the beans sit in are polypropylene - the classic "ceramic burr, plastic everywhere else" hand grinder.
The verdict: Minimal plastic contact
The headline is right - ceramic conical burrs (rust-proof, no metal taste) and a borosilicate (heatproof) glass bowl that the grounds fall into. But the parts the beans actually sit in and pass through - the hopper, the upper main body, the grip, and the lid - are polypropylene plastic, and the hopper lid and non-slip cover are silicone. So beans travel through plastic before reaching the burrs, even though the grounds end up in glass. The metal here is limited to the handle, fixing screw, stopper, and adjustment nut. A perfectly good budget ceramic-burr grinder, but not the plastic-free one it's often assumed to be.

Hario's popular budget hand grinder, an update of the original Skerton with a burr-stabilizing plate for a more even grind. Beans load into the top, you turn the hand crank, and grounds fall into the ~100g glass catch bowl, which doubles as a storage jar with its own lid. Grind size sets via an external nut under the burr. A common first hand grinder at a low price.
Pros

Cons
- Polypropylene hopper and body - beans pass through plastic before the burrs

- Sibling models (Mini-Slim, Skerton Pro) share the ceramic-burr + plastic-body pattern
