A naturally rounded granite or quartzite pebble sourced from glacial deposits in Scotland. These pebbles have been naturally rounded and come in a mix of brown, white, plum and red. Due to their size and difficulty to walk on, we recommend that these are used for borders, water features, pots and raised beds. Choose from either 20-40mm or 30-50mm sized pebbles all delivered in 800kg Bulk Bags directly to your door. A depth of 80-100mm is advised due to size and shape of these pebbles.
