There are eight materials and six textures inside the pack:

-Black marble with polished / leather (matte) / rocky finish.
-White marble with polished / leather (matte) / rocky finish.
-Concrete floor
-Light material

All textures are totally seamless.

The diffuse texture resolution for the black marble is 3000x3000 pixels and for the white marble 2400x2400 pixels.

All the textures (except the displacement) are square.

There are reflection, bump and displacement textures for both the black and the white marble.

VERY IMPORTANT:
Even though the displacement map is active for the rocky stones, I recommend deactivating it and instead of the following:
Select the object (s) to which you want to apply the displacement. Go to modify the tab and select the V-ray displacement modifier. In the properties for that modifier, copy your desired displacement map in the "texture" part. Set the max subdivs to 64 and check "Keep continuity.
