Be honest, how heavy is a box HAC? I adore the 32 cm version but am a bit anxious as box is a heavier leather and well, you can't wear this bag on your shoulder. Has anyone ever purchased a 32 box and not use it because it's too heavy? TIA! P.S. I did consider the 28 cm version but my SA thinks this size doesn't exist for whatever reason. Additionally, I'm a bit hesitant as the last 28 cm (rigid kelly) that I saw had me fretting over how little I can fit in the actual bag. For reference, a 30 cm birkin looks perfect against my frame!
