Review: Good buy! - Great that I can still get these fuses for my aging, country house electrical system. Horrible that they're getting so expensive, even from desertcart. They were a buck or two just a few years ago. Can hardly find them at the hardware store anymore. I'm sure they'll be five bucks a piece soon, so I guess I need to find a lower amp replacement for my space heater.
Review: Only old type fuse i use - I have an old shop that i dont need a modern fuse panel. These are great and easy to change

Overpriced but when you need them you’ll pay it. Just update your electric so you don’t need to buy these old expensive things anymore.
