Driftwood has been treated to remove tannins and has been confirmed to sink. Washed and brushed. Please use for interior decoration, aquariums, etc. Sinking has been confirmed, but the driftwood will be shipped completely dry. Due to the nature of driftwood, it may take several days to sink. The driftwood will be shipped after the water has been removed, so the surface may appear slightly white. This will return to normal after a few days in water. Please understand. No returns or exchanges. Free shipping.
