This is a set of T-fal (Tefal) butterfly glass lids x 2 and seal lids x 2. They are 16cm and 20cm each. These were included in an Ingenio set. I purchased them about six months ago and have only used the pots and handles, but these four items have been stored in their boxes. Although they have never been used, the outer boxes have been opened, and I have taken them out to take photos for the listing, so I have listed them as "Like New." The seal lids do not have protective film, so there are some scratches from rubbing against the glass lids. Please note that these items have been stored by a private individual, so there may be some dust or dirt. There are no smokers or pets in the household.
