Copper buttons in jeans? No, not yet and very rarely do any buttons in general break compared to zippers which break pretty much all the time.

I haven't had any zippers broke in my jeans in like 40 years. Now I'm not sure if I'm the rare exception here.

Hmm, is that a specific brand? I wonder if you might spend more than I do. I'm talking about the cheapest I can find that fit in both cases, so I'm comparing those. I don't buy Levi's or anything like that.

My anecdata from buying cheap thrift store jeans/Target jeans is I've never had a zipper break on them. Have had the pull break off on my luggage though, for a few bags.
