These are very solid and well-made. I had no trouble with irritation, but they are a bit thicker than my other post/wires, so they were a bit less comfortable to put in, but I expect that will pass.

One thing--they look very silver in the photo, but titanium is not so bright--more like a slightly oxidized silver....they didn't look right with a bright silver necklace I wanted to wear, but fine with a slightly tarnished one....
