This is a D.KELLY backpack. I bought it to carry my PC, but I no longer need it, so I'm selling it. The back has a space to store a laptop, and I think it will be useful for business, travel, etc. The opening is large, making it easy to take things out. Height: approx. 46cm, Width: approx. 34cm, Bottom gusset: approx. 13cm #D.KELLY I used it for about 2 months and stored it at home. Please check the images and purchase. It's a clean item. I will fold it up for shipping.
