This has some label remnants, but I couldn't say whether they are original or not. Either way, it's a dark blue thurry and rubbing stone that gives a really nice finish.
Measures 7.25 x 1.5 x .75
I've no idea what these go for these days, so let's say $175 OBO shipped in the US. I'll ship outside the US, but will have to look into cost.
