Small World Slate & Stone is proud to offer these natural slate stones. They are safe for use in your scenery and will not deteriorate in the weather or pet enclosures like resin does. Use these stones as ground cover for your indoor plants. For miniature gardening, they can be grouted together in a path, patio or siding for buildings or walls. Perfect scale for Aquascaping, these stones are easy to incorporate into your tank. Larger pieces can be stacked and glued to form fish caves, caverns and cliffs/mountains or benches/seats. They can broken to create custom sizes. We have sorted and washed these stones and offer them in several size ranges from pathway stones to small scale gravel.
