Create striking contrast in your landscape with Pebble Sino Black Natural 10–20mm. These smooth, natural pebbles range from rich charcoal to soft grey in dry conditions, and transform into an almost jet black when wet—making them especially effective in water features or modern garden designs. Their unpolished surface provides a subtle, organic look that blends beautifully into natural settings.

Supplied in a convenient 20kg bag, ideal for garden beds, pots, and small landscape projects.
