Clear acrylic with brass accents, sized to fit our 500ml diffusers, for a clean, considered display. Each piece is delicate and requires gentle care. Do not allow liquids to pool on the tray and wipe spills immediately. Avoid contact with soap, alcohol and abrasive household cleaning products. These can cause the tray to scratch and become cloudy. Clean your tray with a soft, dry microfiber cloth using straight strokes. Avoid contact with hot items. To preserve clarity, keep out of direct sunlight.
