The green slate I ordered was as described and perfect for weed control in my borders. The delivery couldn't have been any better, at a time stated, the driver even called my mobile to inform me he had arrived. The slate was on pallets in bulk bags and the driver even managed to drop the bags off on my drive. Couldn't of asked for more so I will look at Gravelmaster for future garden projects.
