Description:
BACKGROUND
Field of the invention
[001] Embodiments of the present invention generally relate to a writing instrument and particularly to a multifunctional pen that is provided with a marker, a ball pen and a duster.
Description of Related Art
[002] Both pen and marker have applications for a single user at same time and to fulfill needs, there is always to need to switch from the pen to the marker and vice-versa by the user. For writing on paper, the user needs the pen and simultaneously if the user needs to write on wood, plastic, metal or on any other material, then the user needs the marker. Moreover, any information that is written on a writing surface by using the marker needs to be erased by using a duster. The duster has been used from a very long time by users for erasing the information.
[003] Traditionally, the users need to carry the pen, the marker, and the duster separately that can be a tedious task as sometimes the users forget to carry at least one of, stationery items with them. To overcome the aforementioned issues, some markers have been provided with the duster. However, such markers are bulky and there are chances of quickly drying out of marker ink due to non-provision of any cap on a marker nib of the marker. Moreover, an issue of carrying a separate ball pen is still not resolved, due to which the user needs to buy a new/separate pen.
[004] There is thus a need for an improved and advanced multifunctional pen that can administer the aforementioned issues in a more efficient manner.
