Japanese graphic design firm D-Bros have recently released a new line of stationery called D-Bros for Business. The collection is aimed at working professionals and consists of three essential items - the notebook, the file and the card case. All three designs are elegant and minimal, giving a simplistic take on stationery classics.

The Javaring File allows for all shapes and sizes of paper or documents to be quickly stored away for retrieval later. The Pen and Note is a clever little notebook featuring a pen and paper pocket. And the Paper Card Case is based on a simplistic form born from a single piece of paper and a single fold.

All three products are available for purchase through caina.
