I found something unique and maybe never seen in Japan.
It is the cow boy style ride-on machine!
And I bought some stationery.
When I use mechanical pencil which was found from my desk, that pencil run out of lead and fill it, but did not work well. Because the lead size was not match to it.
Its size was 0.9mm, not 0.5mm which was used popularly in Japan.
I have never used over 0.5mm, only when I needed 0.3mm pencil at mechanical design drawing.
Anyway I got 0.9mm refill today.
