This is an item being sold from a decluttering of my parents' home. The purchase date and usage period are unknown. The tags have been removed from the collars of both items, and I believe they are made of cotton. The light pink striped one has some stains in several places. I've listed them as size M, but please check the photos for the condition and size. They are not for sale separately. Please check the images carefully and purchase only if you are satisfied. Please refrain from purchasing if you are concerned about minor details or are overly sensitive. I will use recycled materials and plan to ship via post. Please be aware of any creases or folds. Thank you very much.
