This is the Japanese version of the Pilot Frixion Ball Clicker,which is the United States variant of the pen.
This is an excellent gel pen and one of the best erasable pens sold today. It’s a very popular choice with students both in the United States (as the Frixion Ball Clicker) and in Japan (as the Frixion Ball Knock).
The term “knock” is not very popular in the US, hence why it’s no surprise to see the different names. In the US people are much more likely to “click” a pen then “knock” it.
