This is a gray Maruman Loose-leaf Binder, mini size, INTO-ONE+. I purchased and used a MIDORI magnet seal that allows you to attach a ballpoint pen. This is a 3-piece set consisting of a smooth-writing ZEBRA mini ballpoint pen and a MIDORI Company belt magnet seal. There are fine scratches and scuffs on the surface of the binder when light is applied (image 14). *The included memo paper is not included as it has been used. You can use it by attaching separately sold loose-leaf memos. Size: 9.5 x 15 cm Maruman maruman Loose-leaf Loose-leaf mini Binder
