What is this?

Found this on Ebay without a description. The ring has four magnets at 12/3/6/9 o’clock. Thinking it might be a paper clip holder?

Nikon branding is on a lot of things - including eyewear.
So it could be related to something that has nothing to do with photography.

Maybe an "Executive Toy" with a spinning centre kept there by the magnets?

That was my thought; a "floating" logo or similar...

My friend used to run a second hand camera store and I'm fairly certain I saw something like this as part of one of his displays, although it was a Minolta promotion if I'm remembering correctly. I think it was used to display/hold lenses or something, not being in itself the thing on display.

Sorry, that was a derailed thought there!
I think it was a type of stand used to display a lense.

That is what I was thinking when I saw it. I’ll see if I can find something that works with it.

Much too light to hold a lens, maybe a filter?

Yeah, I think probably something like that.

Sounds plausible to me.

I’ve been trying different items to see if they will float inside the ring, but no luck so far. Maybe a paper clip a few millimeters shorter than the interior circle might work.

Evidently nothing will float in there just like that. At least not a static item; something with active electromagnets would do the trick and could function as a very basic electromotor. Perhaps that was the gimmick to begin with.
