I purchased this a long time ago. I don't remember when. I've only used it once, if that. There are faint pink stains in the areas circled in red in photos 5 and 6. The yellow circle in photo 4 indicates where these areas are located on the whole item. Also, please note that this item has been inspected by a non-professional, and there may be oversights. It has also been stored at home. Thank you for your understanding.
