Help me find open pant hangers of a proper material?

I really want to get this style of pant hanger:

The issue I'm encountering is that the only options I've found thus far for the material that touches the pants are:
- Cheap rubber/vinyl. Issue: do not trust my vintage/collector pants to constantly be in contact with it.
- Metal. Issue: RUST. Even a slight amount will be death for the pants.

I would love to find ones made of wood or something else reliable. The closest I've come are these:

which are made in Germany of supposedly high-end materials, but I was just informed by them that the contact material is PVC, which is exactly what I want to avoid as it off-breathes and is not recommended for garment preservation.

Lastly, I am set on this type of hanger as the other options (metal clamps, regular hangers, wide wooden clamp, etc.) all have drawbacks for my particular setup and plans.

Thanks you so much, all!
