This Midori Pen Case is very handy, holding up to four of your favourite pens. The adjustable elastic band makes it easy to slide onto your notebook (from B6 to A5 sized) cover, so you never have to go without a writing implement. Its cotton-polyester mix gives it a soft feel yet it's still robust. Plus, there's a pocket with a flap on the outside, designed especially for one pen. Writing convenience? You bet!
