Foldballpen / ballpen

Foldballpen is made of recycled paperboard. It is a material made from waste straw by compression moulding technique. The ballpen refill is compressed in between the paperboard. The production and processing technique is quite simple. It is very convenient and quite easy to use. You can DIY a ballpen with only three steps: Tear off one piece of the paperboard, fold along the dotted line and connect the jagged parts. You can also unfold it and use it as a bookmark.
It saves a lot of room and is convenient for transportation. Besides, the use of environmental-friendly material reduced the pollution caused by mass production.
