The price was reasonably cheap, I thought that it was good to make it firm. I use it at several paces a day for about a year, but it seems to be still used with less deterioration damage. However, I am concerned that the pens in the pocket part is narrow. I think that there are many cases where knock type ballpoint pens etc will not enter. Since I kept a ballpoint pen hooked on the back part, a little back broke. I would like you to improve the pen store slightly.
