Purchased overseas and used once upon returning home. It's in beautiful condition. There are two zippers at the bottom of the bag, and each time you unzip one, the height increases by 13cm (up to a maximum of 26cm). When the zippers are closed, the dimensions are: height 29cm, length 50cm, width 17cm. The height can be a maximum of 55cm (29cm + 26cm). There are no pockets inside, and one pocket outside.
