My child used this to go to school as comfortably as possible, so there are stains and rust on the string parts. Please check the images. There is no name written on it. If you have any questions, please comment before purchasing. 【Comfortable Use】 This back pad uses COOLMAX material, which dissipates heat easily and provides a comfortable feel. 【Size and Design】 The size is 30cm x 25.4cm, which fits perfectly in a child's school backpack.
