So I did what many confused parents would probably do.
I took a photo and tried to figure it out myself first.
After looking around online and comparing photos, I finally found the answer.
It appears to be a Vicks stick, also known as a Vicks nasal inhaler or VapoInhaler.
So no, it is not a USB drive.
It is not a vape.
It is not a charger.
It is not some strange hidden gadget.
It is a small nasal inhaler people use when their nose feels blocked, stuffy, or irritated.
The way it works is pretty simple. Inside the plastic tube, there is usually a small absorbent wick that holds strong-smelling vapors, often with ingredients or scents like menthol and camphor. When someone opens it and inhales through the nostril, the smell gives a cool, fresh feeling that can make the nose feel more open.
That explains the little holes at the top.
