The designer has to design two parts:
1) Box that will hold the Markers - 10 markers in a set - i have attached image of the 10 markers as well to show you color.
2) Pen Label - which will be wrapped around the markers (common for all 10 markers)
Pen labels design will flow from the main packaging design
Please show the box and a single marker together in your design.
Since this is an Art Product - We are looking for something fun .. overall premium feel and not too much clutter
Front part of Box -> We should have only the most important text here - brand, product name , 10 markers, Nib size (6mm). All other things you can remove all the extra text and we can accommodate that on sides and back of the box.
Back part of box -> will show how to use the marker and some other basic texts (this can be taken from another designs .ai file which i have attached)
You can look at chalk effect style for font.
