This is a used, vintage Czech army map case—a smaller version of the Czech Army Map Case. It's a convenient courier or messenger bag with its shoulder strap and easily accessible compartments. It's perfectly suited for tablets and paperwork, pens, notebooks, etc. The bag measures 9" wide by 12" tall and expands to a generous 5" deep. The color may vary slightly as shown in the pictures.
Note: this is a used, military surplus item. Color may be faded in some areas and small blemishes or stains should be expected. This bag is not made of leather, but some kind of vinyl.
