Some service-for-12 sets are designed to stack or nest neatly so pieces save space when stored. Look for product notes that describe stackable or nesting features, since storage compactness varies by design.
While many porcelain sets are microwave-safe, decorative printed or detailed pieces often recommend hand washing to preserve the artwork and finishes.
Service-for-12 sets commonly include matching appetizer/salad plates, bowls and mugs in addition to the 12 dinner plates.
