  • MSI – Beach Pebbles

    Colored polished pebbles lend a fine decorative touch to various installs. Ideal for use as an addition to your landscape, these pebbles protect the soil from temperature extremes, restrain the growth of weeds, and also lend a natural look to your garden. The pebbles are ideal for use near areas that are prone to washouts like under downspouts and may be used at front entrances to add a professional look. All our polished pebbles can be used indoors and outdoors for a unique decorative accent.
