Good basic backpack
Color: Black, Size: 16 Inch
Good size backpack. Unfortunately the front side zip pocket does not fit 13 in laptop. Otherwise it's a pretty generic backpack. Material looks and feel good

Such a Pretty Backpack.
Color: Apricot, Size: 16 Inch
I love this backpack. It's very beautiful and very comfortable to wear. I mainly bought it for a trip to Prague, but I love this bag so much I started using it daily. The quality feels good all around. The zippers are really smooth and the straps are very comfortable. One of my friends happened to take such a liking to it that she ordered her own too. The different pockets allow for easy organization and quick access. It's very stylish and so far, its been quite durable. I've used it for a little less than 5 months and a trip to the other side of the world, but its still holding up.
