Transforms to twice the size to easily accommodate A3 files. A one-of-a-kind leather backpack
From A4 to A3. Transforms to twice the capacity.
In normal use, it's a rectangular backpack that can store A4 documents and a PC, but when you have lots of items to carry, the capacity nearly doubles to hold A3 files. We have created a unique backpack unlike any other in the world that is made of leather and transforms to double the size, big enough to hold A3 documents.
A large-capacity leather backpack that comfortably holds both A3 files and shoes.
We achieved a large capacity that can easily hold A3 files, making it possible to carry around design drawings and proposal documents neatly. You can also use it as a high-capacity bag that can hold items for going to school or sports after work. We tend to carry around shoes in a separate bag, but with the backpack's ample body width and gusset size, they can fit snugly inside the bag.
A wealth of exterior pockets spares you from having to open the bag to insert and take out items.
To make it easy to store large items in the main space, there are no small pockets on which things can get snagged. Instead, we equipped the bag's exterior with enough pockets so that you can quickly insert and remove items just by opening and closing the fastener. There is a pocket on each side that can hold card cases and key cases, and the front has a double-opening pocket that can hold a long wallet.
