[Kuretake] Empty Pen Cartridge (Set of 5)

An empty pen is an "empty" pen without ink. You can easily create your own fountain pen by adding ink. You can fill it with your favorite colored ink to create a pen with a unique hue for your daily coloring. A one-of-a-kind empty pen also makes a thoughtful gift, perfect for conveying your sentiments. This is a replacement cartridge for the ECF160-601/ECF160-602.
