At a genuine price?

How about cutting open a few samples of suspected counterfeit fuses to see what's inside them? I'd be curious to see just how junky they are. I'm sure someone could make a reasonable quality approximation of the real deal for a lot less but I'm betting most of the fakes are just a cheap fuse element inside a cardboard or plastic tube.

I remember you mentioning it and I looked at your Amazon store but did not see them listed.

I bought a few and as I mentioned I plan to check the filler of the one after I check the trip current.   I think depending what I see there, I may hook one up to the transient generator.  Not very scientific but if there is no filler we may get a small bang. 

Even Asia Fuse are filled...

Not impossible, but ... they'd have to be total cheapskates to not put filler in them. You can get sand for free almost anywhere in the world.

Nothing is free.  First they have to dig, sift, clean, dry and then install it.  That's a lot of cost...
