The Truth Behind Pen Caps with Holes: A Smart Design with a Big Purpose

More Than Just Safety: Other Benefits of the Hole

Besides the critical safety aspect, the hole also serves additional functions:

• Pressure Regulation: When capping the pen, the hole helps regulate pressure inside the cap, preventing a vacuum that makes it hard to remove the cap.
• Ink Drying Prevention: It allows some airflow, which can help prevent excessive moisture buildup inside the cap, preserving the ink quality.
• Manufacturing Efficiency: The hole can also help during the production process by reducing material and weight slightly.

How to Use Your Pen Safely
