Found one of these in a wrecking yard a few years ago all buggered up. But when I tried writing with it, oh my God, it was so SMOOTH!It has just the right sized barrel and a nice silicone band that is soft and not slippery to hold onto. It does not look like a $25.00 pen but an inexpensive writing implement. But, it is for work or pleasure and just fun to write with.The biggest decision you will have to make is whether to use a medium or a broad point (or finer). Following the name of the pen on the pocket clip is a number. The number on the "BOLD" or broad line pen is the number 10. This is my preference but I am not writing a book.The medium point is marked 07 and writes with a finer line. The pen is also available in Fine and Extra Fine - great for a book-keeper or someone making fine notes.I assume that the 10 on the "Bold" stand for 1 mm. width. Logically, the 07 would stand for 0.7 mm on the finer and Medium point.Please also note that all the fillers are marked with the size of the point on the filler body itself. That means if you get them out of the package, you CANNOT get them mixed up.The pocket clip on the pen is made of plastic and part of the pen. If you carry in a "fat pocket", you can "stress" the plastic and the clip will fall off. Save an empty pen or two to change your still working filler into a different pen body (they are threaded together so the come apart/go back together easily.)Remember also that the wider the point, the quicker your ink will be gone. While Pilot claims their gel ink lasts twice as long as anyone else, you will "write them dry" if you use them regularly.When you consider buying them, decide what colors you want (if any), and also price shop the complete pen with the fillers. Sometimes the whole pens don't cost any more that the fillers as whole pens are often sales priced and fillers alone are not. So check price on both before ordering.I hope this information will help in making a buying decision. Please click "Yes" below this line if this review was helpful to you.
