Pilot BRFS-10F-L Ballpoint Pen Blue Refill set of 10

This a D1 refill .7mm which I thought would be a medium point since the other offering is a .5mm and is even finer pointed. I don't like fine point pens much as it does not fit my writing style. It's a bright blue color, a but on the lighter side of blue. Just something to be aware of. They come individually wrapped in a paper box that is written all over in Japanese. Again be warned these are what I would consider a fine point refill. Though it is a D1 it fits most of my pens but not all. I got it for the Tombow Zoom 727 and it fits loose in the D1 slot so the refill slides out. Oh well.It took a lot of start up for it to write, I wrote continuously back and forth lines just to get it to have consistent ink flow. Maybe I got old stock or they are all like this, I don't know. I knocked off 1 star for not fitting in all D1 slots and another star for the slow start. If you like light blue ink in a fine point this is for you. If not move on.
