This oyster with trees in blue pots is the perfect shell for someone who loves topiary. Our Decoupaged Oyster Shells have a high gloss, glass-like finish which brings out the color. The shell has been slightly ground along their edges to reduce scratches and is trimmed in a metallic gold. All of our shells are sealed to prevent tarnishing and add a further layer of protection. Oyster shells are between 4 and 5 inches and each shell is unique. All my shells are from the Rappahannock River, Virginia.
