It's arrived. It's 8x2x1/2". It is a medium grey colour dry and nearly black wet.The edges have been beveled, the two "faces" have been "milled" rough, the slate is very dense and stable (a bit like me).Where it has been cut on the ends, it is very smooth,far smoother than the large surfaces or sides. I think it is more abrasive than my Tam.
It came in a cardboard box.
