Existing punches have difficulty of finding the correct location of making a hole. "Transparent punch" lets a user instinctively make hole at the correct location he/she wants because it uses transparent material so that paper seen through such material.
The structural part was improved as the previous punch structure was put upside down. So, we can now see the paper intuitively even when using the punch without its structure hiding the paper. On the transparent part of the punch, there is a red ring, and the blade is punched upward from the bottom of it.
