These pebbles come in a specially designed bag that makes application and storage easy. Use these mixed pebbles in residential or commercial spaces for adding a beautiful rockscape design in planters, along walkways, as decorative accents, and in creative landscaping. The polish will wear due to exposure in outdoor environment conditions. The Rain Forest mixed polished pebbles are recommended for indoor or covered patio use.
