To use this vase, simply fill it with water and place your favorite flowers inside. You can also use it as a decorative item on its own without flowers. When it comes to maintenance, clean it gently with a soft, damp cloth to keep its glazed surface looking shiny. Avoid using abrasive cleaners as they may scratch the ceramic. Keep it away from direct sunlight and extreme temperatures to prevent any damage to the glaze. And always handle it with care as it's a delicate vintage piece.
