Yeah I ordered a stone on Nov 19-20th? and got it today, Dec 24th. It only required one email, after about 3 weeks to inquire about my order as I had not heard anything about it being shipped after initial confirmation. Turns out he'd forgot completely and sent it a day or two later by EMS with refunded shipping. From my experience Takeshi is trustworthy, just requires a bit of patience as he's not the speediest or most contactable vendor.
On the plus side, the stone I got seems to be a gem! For what its worth, I would also order from him again. I definitely recommend EMS to any prospective buyers, just for peace of mind.
