"The Onyx Black chippings are great for borders, patios, walkways and driveways. The decorative black stones are ideal for adding texture and definition to your outdoor areas. Use a combination of chippings and other materials, such as slate or pebbles, to make a statement in your garden. The Large Pack and Bulk Bag are the two available sizes of the premium chippings. We recommend a minimum depth of 35mm when calculating how many bags you’ll require. Please keep in mind that natural materials will vary in size and colour, with some being significantly different."
