T-fal Seal Lid Storage Lids for Pots, Set of 2: 20cm / 18cm This is a set of two T-fal storage lids, 20cm and 18cm. They seal tightly for refrigerator storage, preventing odors from escaping. They can be stacked for space-saving convenience. I purchased these and stored them, hardly using them. Being plastic, there are some scratches and scuffs on the surface. Please refrain from purchasing if you are overly concerned about minor imperfections due to home storage. Please understand that this is a used item, and there may be oversights. I will ship them in a bag as is.
