My child used this for about a year. Both the zipper and buttons close securely. The shoulder straps can be adjusted to extend long enough for an adult to use. Four pockets. Approximate dimensions (cm): 24 x 21 Depth: 11 x 21 Black ◼️There are small white stains and some wear on the surface. You could probably repair the white spots with a permanent marker, etc. Please check the photos. I was planning to pack it small, but it looks like it will be a size 60, so I've adjusted the price. m(__)m
