Rosewood is a Brazilian hardwood. I have some recorders made from rosewood and they have a beautiful reddish brown grain which I don't see in that picture. I suspect the pipe is made of some sort of sawdust and resin. I'd be wary.
Hmmm..... Too bad. There are some nice pipe from Rohan on eBay, but I guess I wont risk it. Too bad also becuse finally something I won't have to pay shippment for since they are from Israel :D .
