Slate Hollolith 600

Quite a large stone in blue or plum. We start with an oblong or wider slate stone and drilled a large borehole through the front, cut the base, and drill a water hole 32mm wide from the base to the large borehole. This allows for water to be pumped up and runs out of the bottom of the hole. Very different from the natural monolith. Much more contemporary and modern. The weight can be up to 80kg.
