One circular white lid for a cup, approximately 7.5cm in diameter. A straw can be inserted. One circular white lid for a cup, approximately 7cm in diameter. This is a lid for a mug. If opened and closed frequently, the lid may crack before the main body, but in my house, we didn't use the lid, and the main body faded. I thought someone who needs it might want it, as I won't be using it anymore. The smaller size should fit small cups for children. - Color: White - Shape: Circular - Diameter: Approximately 4.7cm Thank you for looking.
