I thought about buying one a few months ago but it's a natural like others have said & you just can't put a number on the grit of a natural. The seller claimed it was from Italy but could never prove it. I think it is in another thread on here. I'm not sure but I think he is or used to be a member on here. You can find it on eBay from 2 sellers mainly & if you look at the location each seller is from, it is the same state. He has a premium grade & claims "Individually razor tested". BS!!! He also says they are "hand picked". Okay, whatever. The OP may have bought his from a different seller, I don't know. When one person says it is from Italy & another says South America, red flags go up for me! I'm glad I didn't buy it. I bought a Snow White instead. At least I know what I got plus I have a few naturals too & I love them. I truly think the OP would be much happier with a different natural.
There is a guy selling a used right now from VA & he basically says what the other sellers say. Besides that, if it is so good, why is he selling it.
