This is a rock climbing hang board/ finger board from Liuboduil.  It is a bit different from a lot of other boards out there right now in that it feels like stone.  I am not sure if it is natural or cultured (probably cultured) but has the feel of a fine grained granite.  What it doesn't feel like is wood or plastic.  No disrespect to those textures but sometimes stone just feels good. The holds are smooth but not slippery.
