The tankbag notebook 15" is made from original convertible top material, as used in automobile production. On average, 80% "leftovers" from convertible top production were used, and 20% was new convertible top material. The material is virtually waterproof, colorfast, and dimensionally stable, meaning it doesn't stretch. The bag is carried by the short handle. It opens fan-shaped and is divided into three compartments by two well-padded dividers. The compartment for the notebook is in the middle, providing optimal protection from the outside. The side interior compartments can accommodate A4 documents, charging cables, a cell phone, and other personal accessories. The clear bag body creates an elegant and timeless feel.
