This was my first JHerbin purchase months ago and have been loyal fan since.
Shade of blue is magic, especially on white white paper, actually jumps off the
page. Second purchase was 1670 Anniversary Formula...equally impressed with it.
Will not be without either of these in the furure. I've noticed they work
equally well in all of my pens (Sheaffer, Safari, Al-Star, Kaweco), but I'm
especially favorable toward the Kaweco F or M nib with Saphir refill. Writing is
smooth (zero scratchiness), flow is excellent and lines are perfect thickness.
To top it off, the notch in JHerbin bottle is custom made for storing a Kaweco
that is loaded and ready to perform. Quality of JHerbin and JetPens goes
Have now used this pen (silver finish) and three nibs (F, M, B) for about a
year. I'm a 6'2" 200 lb guy and this pen is extremely comfortable in my large
hand. Of all my fountain pens (Sheaffer, Safarfi, Al-Star, Kaweco), this is
clearly a favorite. Most used nibs are F and M but like to work with all three.
Masterpiece in design, construction, reliability and durability. The medal
threads mesh smooth as butter. Capped, the pen is like holding a Cross
ballpoint...about same length, same thickness, just about tenth the weight; also
about same size/wt as Fisher bullet pen. Was skeptical before purchase but the
more I use it the more I appreciate the genius behind it. Even the nibs are
about easiest and most durable I've ever experienced. The small cartridges are
just right size and sturdy enough to refill and use for other inks/colors. All
pen colors are very appealing and ten-star service from folks at JetPens is
unbeatable. Add one or two of these guys to your arsenal...you won't regret it.
