Seconding everything here, but emphasizing point 2. Some folks have metal allergies or sensitivities - nickel is a common one, for example.

Surgical steel is usually safe, but still best to confirm she doesn’t have any particular sensitivities.

The only time I saw one was on a cheap dollar store plug. I immediately thought it was defective.

This is neat info!

Thank you! I hadn’t seen this community. I’ll definitely check it out!

I might go this route; thank you!!
