Red White Line Rock Please note: the price is per kg Weight and size always varies by type of rock. We will try to mix and match your chosen weight as closely as possible, but this can't always be guaranteed! If you have a preference in number of rocks or size, please leave a note during checkout, and we will try to accommodate where possible. Since this is a natural product individual rocks will vary. You are welcome to pick out your own pieces by visiting our shop in Mansfield. Always rinse and clean rocks before adding them!
