3. USB Drives
Today, a USB drive is something you must have in your home. However, since they are so tiny, we tend to lose them shortly after we purchase them. I think that USB drives are one of the best selling products in the whole world, not only in Pakistan, so it is not unusual for me to see that the Pakistani people have bought so many USB drives. Since they are so useful and inexpensive at the same time, they will be one of the best selling products for a long time, that is for sure.
