Features 

• PERFORATED LIDS: The lid protects your microwave from splatters and spots. The BPA-free plastic and silicone topper covers food to encourage even cooking and to keep food inside for a cleaner microwave. Small holes in the top of the lid allow steam to escape, encouraging airflow to prevent condensation buildup. Lid is dishwasher safe.
• EASY STORAGE: Collapsible cover pops up to 3" to cover tall dishes, piles of food, and shallow bowls. The cover collapses to 0.75" for easy storage. Cover can also be used flat to cover large bowls to prevent splattering for a cleaner microwave.
• HEAT RESISTANT: BPA-free plastic and silicone for a heat-resistant, food-safe cover. Won't melt in the microwave or dishwasher.
