I just did a search on a number of Chinese sellers, and it seems like $2.5 is a reasonable price. Some sellers even showed their formal invoice for these goods and some showed original package and import documents.

A lot of counterfeit things are sold in "original" packaging. Some eevblog members bought multimeter fuses from China and they were fake.

It could be many sellers selling fake, but it is impossible to see all sellers sell fake.
All search results show ~$2.5 price range.

Why not, if all of you are looking is in the same price range.

Get real, it's not a "$35 fuse" and never was. That someone tries to charge you that much for it - well, that's a whole different story.

I think it's more an academic debate than anything. :-DD
The danger with these fake fuses only exists when measuring on high energy circuits.
First, this is not the majority of users.
Next, industrial electricity and power electronics are disciplines where technicians/engineers must have the proper training.
This is my area, I know of what I am speaking about.
1) NEVER measure a current on high-energy circuit with a multimeter, always with a current clamp. :-+
2) we always check and recheck before making a measure ... the possibility of error or distraction is excluded.
3) an industrial electrician / power electronics engineer use his multimeter WITHOUT FUSE for safety :-+
To measure the voltage of a busbar 5000A 550Vcc is not done without extreme précautions because even the original fuse will probably not interrupt such a high DC voltage with high energy.
Jeroen3:
1) Sometimes you're an idiot and measure Volts while the meter is connected in Amps. Flukes will beep at you. But you won't hear that in all use cases. This will cause a plant-wide blackout when you're fixing the 10kV load sharing.
2) When you're doing repeated work. This will be a point of mistakes.
3) He doesn't have a multimeter. He has an Voltage Tester. Such as an Fluke T90.
Sometimes you have to measure busbars, but you don't do this on the live busbars unless you can't possibly do it elsewhere. Often, busbars are near some kind of cabinet with control and/or measure electronics, and you can measure after the fuses or mcb.

I've seen the shrapnel of ceramic fuses embedded in the inner case of an ancient television,

I did a test where we put very cheap multi-meter which had a glass fuse across a 440V supply (the meter was rated for 600V). I found part of the meter case on the other side of the room. We drew enough current to trip the 75A breaker.
