pinclip by jeongju choe from korea

we need to use a pin to fix a paper in our every life.
on fixing the paper, we can not help to make damage on the paper.

Is there better way to fix the paper on a board?
I concerned about it and eventually I got an idea as combine pin and clip which using it clip a paper.

In order to fix the paper, we don't need to make any hole on it anymore.

it's very easy. Just clip it and fix it!
