We designed our Karsan bags to protect your makeup and skincare from heat damage — but here’s a fun surprise:
customers started using them for their phones too.
And yep… it works.
☀️ Why Phones Overheat So Fast
If you’ve ever left your phone in the car and come back to that dreaded “iPhone needs to cool down” screen, you already know:
-
Direct sunlight + hot interior = 🔥 no good
-
Overheating can slow your phone, damage your battery, or shut it down completely
-
A regular bag or pouch? Doesn’t do anything to stop it
🧊 Why the Karsan Bag Works
Our bags are insulated with heat-reflective lining — originally to stop lipsticks and serums from melting.
But guess what? That same protection slows down the heat transfer around your tech, too.
✅ What Fits Inside
-
Your phone (yes, even the big one)
-
AirPods or earbuds
-
Portable chargers
-
Cables
-
Sunscreen stick + balm (yes, still beauty girl coded)
Toss it in your front seat, center console, or beach bag — and your phone stays chill longer.
🔁 Real-Life Use Case:
Someone on TikTok literally commented asking if the bag could be used to keep their phone cool.
The answer? Yes. And now we do too.
💼 Reminder:
It’s still a beauty bag.
But now it’s also your hot car survival kit.
