WB355 Conch Shell. Approximately 5x3 inches. Hand Carved Wooden Printing Block from India. Use with paint, deColourant, thickened dye and more to create your own surface designs on fabric and paper. Our printing blocks are carved by master craftsman from hard wood, which makes them very durable; to ensure they stand up to lots of use, they are treated with olive oil. Note: because each block is hand carved, sizes are approximate and designs may differ slightly from the photograph.
