W time is about the summer of 2021. I heard the news that a shirt with matching numbers or underwear sells well.
Just thinking about whether it can be made into a pen, which just fits the theme of the college entrance examination students, and the meaning is also very good.
I mentioned this idea to boss because it involves many structural problems,
Finally, this pen was made by structural designers who changed a lot of structures.
I left my job around July 2021, applied for an appearance patent in September 2021, and the designer's signature was not mine. Its practice is not evaluated here.
However, it is also very good for one's own ideas to be recognized, and the products are made.
