I used various ballpoint pens for many years but this is the best 2. If you use it for a long time you will want to change it to other things but you will not get tired at all and now this is the best. I also like Knock formula.
Because it is not readily sold to shops, it is very helpful to purchase with Monotaro san. I prefer a thin core because of its high writing pressure. The ink also goes very smoothly and it is very easy to write. It is nice to meet a very good product.
7 mm and 5 mm are used depending on the application. It is useful because it can be used without stress and slippery and ink irregularities are not bothersome. I have been using various things. If you think of Cospa, you can use it for a long time. It is recommended (* ^ _ ^ *)
