I have been using Only one pen for any situation. I would always put the pen in the folder attached to the schedule book. First I found it was three years ago. Before that I often lost a pen and often bought another one. However it costed and wasteful. I used to be depressed whenever I found the pen which I had lost after I bought another one. So I was trying to find my favorite special pen.
Meanwhile I found my favorite one. It contains 4 color ballpoint pen and one pencil. Even though it contains many abilities, it is not fat. It is easy to hold for my little hand and easy to bring for anywhere.
I will write about it again in tomorrow's blog. I am happening to buy another one though I really love it!
