Coco Fusen Sticky Notes Cool Grey MCoco Fusen are sticky note tabs that are useful in office, study, journaling, and other writing situations. Each pad has 30 notes. Unlike traditional sticky note paper, which is limited to being placed in a storage place like a pen case or pouch, it can be used in various situations as needed. Due to their filmy surface, ballpoint pens, pencils, and permanent markers are best for writing on these sticky notes. Water based inks may not write as well.
