About 10 years ago, I think that there was no "entering" ... I remember buying it bespoke, but since I found found out this time, I purchased it immediately. Thank you very much.
In Monotaro, I have various colors of blue, red, so I think I will purchase it from next time.
It is natural because it is a sharp tip, but the seal imprint is also clearer and the main body is firm. I used disposable things up to now, but it is good that this product can be used repeatedly by exchanging ink cartridges.
