This is an Ergobaby nursing pillow. It was used for two infants. When the surface fabric is brushed in the opposite direction, it appears as shown in the photo. Please understand that this is not a stain (I apologize for my poor explanation). It has a handle, making it easy to carry. The cover can be removed and washed, but the main body is difficult to wash. Therefore, there are some stains, although they are not easily visible in the photos. There is no original box or instruction manual. - Brand: ergobaby - Color: Gray系 (Gray-toned) - Shape: C-shaped - Material: Fabric - Zipper: Yes Thank you for looking.
