I used this for commuting for about a year, but I no longer need it, so I'm selling it. It has many pockets, making it convenient for carrying a lot of luggage. It's equipped with an earphone jack & USB port on the side for direct connection of earphones and USB devices. The back is designed to pass through a suitcase handle, making it useful as a carry-on bag in travel situations. 【Details】 ■Size: 46cm x 31cm x 16cm ■Weight: 1.04kg ■Color: ・Black ■Width of the handle pass-through: 17cm ■Capacity: 21L
