Thank you for viewing. I purchased these at a T-fal specialty store. I bought them, but both have been sitting unused in the cupboard. They are from about 10 years ago. Both are new and unused. They are 16 centimeters. I will also include the plastic seal lids. They are convenient for storing food in the refrigerator. The seal lids show some minor scratches and signs of aging. - Shape: Round - Material: Glass and plastic - Features: With steam vent - Usage: Pot lid Thank you.
