There are many pens in the Japanese hundred-dollar store. Generally 105 yen can buy two or three pens, not all of which are from China, but also pens imported from abroad, such as Bic and paper-mate. . . But they are all ballpoint pens, and there are 100 yen in the pens, which are sailors from Syaraku, Japan, but only the pens themselves, so it is more cost-effective to spend 100 yen on five ink packs. In addition, the pencil usage rate in Japan is very high. I suggest you buy mechanical pencils in China or Japan. Domestic products are cheaper, and Japan has many choices and good quality. You can buy lead cores in China for a long time.
