Korean designer Giha Woo's latest work is called Clip + pen. Known for creating various useful writing utensils, Woo has added to the collection with this minimalist pen. I love the incorporation of an actual paper clip as a fastener because it's kind of quirky. Either way, it'll let you attach the pen any notepad or you can simply use the cap as a normal paper clip.
Giha Woo's clip + pen is available either in blue or white.
