Hello adrspach,
Item number is 130567763011. Probably is the stone you are speaking.
So, isn't this stone a DT? In fact on the advertisement the words "dragon" and "tongue" aren't mentioned. I though that it is a DT from description (approx 12000 grit, extremely fine stone, it is very hard, it is a slow stone, etc…).
I admit that my knowledge in stones is very limited, so an error of mine is highly probable.
Bye
Alessandro
