Schneider Color Pen Color Marker Link-It Fineliner 16 Color Set 19 Pen Tip Size: 0.4mm Ultra Fine I'm selling these because I no longer use them! I used them for about six months, so some colors are running low. Please check the fourth image. (Especially emerald green, light blue, and light pink are difficult to write with.) You can also use them by attaching two pens together as shown in the fifth image. I received these as a gift, so I don't know the retail price, but on Amazon, a new set seems to cost around 11,000 yen!
