I agree with all of the above. At first, I thought he was trying to skirt something by charging so much on shipping, but after viewing the royal mail page, I see that confirmed royal mail just costs a mint. I wish he would ship more things economy, but I understand with all of the international shipping why he doesn't. I would probably buy a half dozen more stones from him if the stuff would be sent surface mail, but I don't want to go to the trouble to find out if he'll go there.

As far as the names, hopefully most people know there's no free lunch, at least not without risk. Grit ratings - well except the most experienced always overstate the fineness of natural stones. I've never figured out why. There are precious few natural stones with 1/2 micron grit particles and nothing larger...maybe none.
