Center Cap Recommendation?

I just took off a wheel cover and observed that the hubs might benefit from center caps even with wheel covers.

Can anyone recommend some?
They don't have to have a logo, just black and fit.

Thanks.
(I will search the forums as well, LOL.)

 

Well, I did the search and came up with the eBay items, but requires a wait to arrive from China.
I found what appears to be a similar one on Amazon. We'll see I guess.

On a side note, it was harder to put the wheel cover back on compared to pulling it off. A rubber mallet was involved.

 

Well, the Amazon-sourced caps came and I installed them.
They fit perfect.
Damn, those hubcaps are hard to get back on.
