We designed a shelf line to be used in the indoor office space of the Ship and Ocean Research Institute. We designed a wide shelf line to match the large size ratio of about 3M and designed it to consider the convenience of using the monitor arm by composing it into 3 modules. In order to focus on the monitor and create a bright and refreshing space, the white color and the shelf line were made in a round shape so that it can be manufactured in FRP form.
