Properties and Benefits: These large decorative pebbles/ cobbles are flint based with a classic blue/ grey colour and sections of yellow. They are river tumbled and hence very well rounded. This makes them ideal for making attractive water features in your garden. They also look very effective when placed to form features in their own right. Another great use for these decorative river pebbles is to set them in to a concrete path or wall. This makes what would normally be a boring feature a charming focal point. Approximate coverage of 0.6m2 per 25kg bag at 25mm (1 inch) thick. These decorative pebbles have been photographed in a wet condition.
