• Don't you accidentally forget to store the tip of a plastic ball point pen and the dirt on the chest pocket becomes noticeable? Have you ever dropped something in your breast pocket when you look down? Also, don't you forget to take it when you wash your clothes and stain them with ink? A 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. By simply putting the clip in the breast pocket and holding it in the pocket mouth, you can prevent it from falling and work with peace of mind.
