This is a pouch that came with a 16 Tea PET bottle. The size is shown in the first photo. It was attached to the PET bottle box for sale, so there are tape marks from when it was removed from the box. It is not for the purpose of keeping things cold, but is a pouch made of a leisure sheet material. It has been stored at home for a while, but is unused. It will be compressed for shipping to reduce its thickness.
