This Buddhist altar set features a gentle, rounded design. The brass is finished with an elegant, lustrous purple finish. The flower vase is cast, but has a common base, ensuring no risk of water leakage even after many years. The incense holder is luxuriously crafted by carving it out of brass. [Handling Precautions/Care Instructions] Polishing with metal polish or chemicals may remove the surface coating, so please clean with a soft, dry cloth. Because it is made of brass, a patina may develop over time.
