My Ink Holder file holds four full sized inks and has sliding trays for easy access. You can cut multiples and adhere the sides or tops/bottoms together to make larger storage units! The file will cut on both the 12" x 12" and 8-1/2" x 12" mats and it works several different ink brands including Memento, Stayz On, Versamark, Colorbox just to name a few! This unit will also store Washi tape when sitting with the tabs pointing up!
