I like the idea of stacking trays or stacking your information and easily being able to move your “stack” around. Aesthetically the structure and design are nice. I really couldn’t picture myself using these but maybe you can?
“Bon Drawer” is the drawer which piled up a “Bon” made by the veneer of the oak. ( A meaning of “Bon”, the word “tray” is close in English.)You cannot only use “bon drawer” as withdrawals but also you take a drawer out as a “Bon”. The rail for the “Bon” is just a flat bar attached to a frame.The frame is made by minimum structure for the drawer.In addition, you can move them easily by the wheel and handle attached the frame.
