These panty liners can be used to check your fertility window. There are 5 liners per pack, and there are two boxes. One box is damaged as shown in the photo. However, the liners are unused and clean, so I think you can still use them! If you don't need the box, I can send them without it, so feel free to comment. - Brand: Unicharm - Product Name: Panty Liners - Quantity: 5 liners per pack - Features: Can be used to check your fertility window - How to use: Can be linked with an app Thank you for looking.
