A small project of the school, a small gift made for a hardware company, is designed with multi-color ballpoint pens as elements. In addition to the basic screwdriver bit, it also has searchlights, rulers, hammers and magnets.
There are still many deficiencies. I hope I can have a good time.

In order to facilitate the selection of the screwdriver bit, the front end of the main body is a transparent layer, which can be easily observed. At the same time, the size symbol of the screwdriver bit is also engraved on the button.
