A paper clip is a paper clip, which is different from a pin. It is a paper clip made of a wire that is bent back and forth. The paper clip seems to be the simplest of all inventions. It is just a small piece of curved wire that covers the paper. But the paper clip has been repeatedly designed before making the shape we use today.
In the office, the most common use of paper clips is to clip files and put paper and folders together to play a fixed role.
The paper clip can also be used as a raw material for DIY.
After straightening, you can make a variety of crafts.
