MIDORI Book Band Pen Case Transparent Sepia, for B6~A5 size, 1 piece I only bought one, but when I opened the package, there were two inside, so I'm offering one for sale. I thought it was the store's mistake, but after checking, I realized I had mistakenly purchased two. How sad. The return shipping costs are high due to my own reasons, so I'm listing it here. I've taken pictures of the item out of the bag for clarity, but the one I'm selling is the unopened one in the 3rd and 4th photos, '1 piece'. Images 5-7 show an example of it attached to a thick A5 notebook. You can put 4 or 5 pens in it. Also, there's extra room in the rubber band adjuster, so the paper doesn't buckle, making it a nice product. I will ship it via Rakuraku Mercari anonymous delivery. Instant purchase is OK!
