Inspired by vintage mailboxes in the US, this noteworthy (ha!) bag is REALLY two bags in one! By simply adjusting the strap, you can go from a shoulder bag to a backpack! Though the bag is slender, the elongated design creates room for your tablet, wallet and more n the interior while a zippered compartment on the inside of the exterior provides additional secure storage space. There’s even enough space for… gasp… an “old-fashioned book,” Van Eeghen specifically notes.
