Do unused fuses have a shelf life?

I'm curious to know if unused fuses have a shelf life. It seems like many products do, whether it's food or electronics, and I'm wondering if the same applies to fuses. After all, they're designed to protect circuits from overcurrents, so it stands to reason that their ability to do so might degrade over time. But is there any truth to this? Do unused fuses really have a shelf life, or can they be stored indefinitely and still function properly when needed? I'd appreciate any insight you can provide on this topic.
