Finish looks solid.
As others have said… just a plug. But the finish appears to be solid leading me to be less concerned about flaking and oxidizing.

Packaged in the right box but box contained wrong size.
Quality was very good BUT I ordered 3/4" plugs, recvd box marked as 3/4" but it contained 1" plugs. Returned product and no rush on my part so I requested a replacement, opposed to a refund.

Plugged a hole, nice packaging and nice to have 3x instead of 1x
