*Why Pen Caps Have Holes: A Clever Design You Might Overlook**
Pen caps aren’t just there to protect the tip—they’re carefully designed with tiny holes for important reasons.
**Safety First:**
The hole helps prevent choking by allowing air to pass through if the cap is accidentally swallowed.
**Better Ink Flow:**
It helps equalize pressure inside the pen, preventing leaks and keeping the ink flowing smoothly.
**Cheaper Manufacturing:**
The hole reduces material use and speeds up production, saving costs when making millions of caps.
**Stylish Design:**
Some brands use the hole as a design feature to make their pens more recognizable.
Next time you see a pen cap, you’ll know—it’s not just a random hole, but smart, thoughtful engineering!
