After opening the package immediately upset, it turns out the trolley is separate and the size is not included, so the plane will not pass in any way and in general, it is very sad, the backpack in the sense, want to send it to you cheaper, what's the seller? The seller without problems except the description of the backpack itself. The trolley itself looks strange and unreliable, the backpack is not functional and uncomfortable, in general i do not advise!
