This aluminum plate with a lift-up holder allows for defrosting approximately 9 times faster. - Product Name: Rapid Defrosting Aluminum Plate - Features: With lift-up holder - Operating Temperature Range: -65℃ to +250℃ - Defrosting Time: Approximately 9 times faster - Size: Plate size: 298x210x12mm I took the contents out for product photography and put them back.
