Every trinket tray is hand-poured with subtle imperfections and characteristics like air bubbles and color variations. Just like in nature, these are what make it special. Each trinket tray is mixed, poured, and meticulously sealed by hand. Care instruction: Please avoid submerging them in water or getting them wet for a long period. Simply clean it with a damp cloth and let it dry. All our products are sealed and water resistant, however, they can still absorb liquids and waxes causing marks and stains. Please keep these products indoors as the outdoor elements can shorten their lifespan and cause blemishes. Not suitable as a food dish or in the dishwasher or microwave.
