I purchased this at Yofuku no Aoyama. It is an I.M.G.N. bag. I have used it about twice and stored it in the closet. Approximate size: Height: about 27cm Width: about 40cm Depth: about 12cm There are studs on the bottom, so it won't get dirty even if you put it on the floor. The inside is divided into three large compartments (each large enough for A3 size or larger), the middle compartment has a zipper, and the two side compartments have magnets. There are many small pockets inside for sorting, making it convenient for job hunting, etc. There is one pocket on the outside.
