• Don't you accidentally forget to store the pen tip of a ballpoint pen and the dirt on the chest pocket becomes noticeable?
• Have you ever dropped something in your chest pocket when you looked down?
• Also, is there a case where you forget to take it when you wash your clothes and the ink stains them?
• The chest pocket pen case can handle such problems.
• By using the pen case for the breast pocket, you can prevent ink from blotting or forgetting to take it out, or you can prevent it from falling by simply putting the clip in the breast pocket and holding it in the pocket mouth.
