Sun-Star Ninipie Pen & Marker - 6 Color Set

Sun-Star Ninipie Pen & Marker is a uniquely designed Japanese writing tool that combines two everyday functions into one compact pen. Sun-Star describes Ninipie as a new kind of pen that brings together “write” and “highlight” in a single tip structure, so you do not have to switch between separate pens while studying or taking notes.

The pen side uses a 0.5 mm needle pen for writing fine notes, while the marker side is designed for smooth highlighting. The user switches between the two simply by rotating the body, making the pen especially convenient for school, office work, planners, and slim pen cases. Sun-Star also notes that using one pen instead of two can help reduce the number of pens you carry, which makes Ninipie especially appealing for people who like compact stationery.  

Another practical point is the color system. Retail and press descriptions explain that the needle pen ink and marker ink are different but coordinated, so highlighted text stays easy to read. Sun-Star also emphasizes the use of soft, easy-to-use colors, with a clean white barrel and paired ink tones that look cute while still being functional for notes and study materials.
