Vevor black river rocks are natural polished pebbles designed for landscaping, plant displays, aquariums, and decorative indoor or outdoor use. The 15 lb bag includes mixed oval, round, and irregular shapes with natural textures and patterns. Their smooth polished surface helps protect hands and plant roots during handling and placement. These stones help retain soil moisture, reduce weed growth, and support drainage for healthier plants. The black finish adds a clean decorative look to gardens, pots, pathways, and water features.
