uni-ballJetstream RT Refill 2 Pack, 1.0mm Medium Blue, Wirecutter Best Pen, Ballpoint Ink | Office Supplies, Pens, Ballpoint Pen, Colored Pens

Product was as expected but shipping took about a week.

I consistently and regularly purchase these refills, because the Jetstream Pen by uni-ball is the BEST PEN I HAVE EVER USED IN MY ENTIRE LIFE. I actually get hyped out, when co-workers reach for this pen to "borrow." Why, because I know the minute they try it, they will purposely keep it, since it writes so DAMN GOOD!!!I usually get "blue" since I like the look of blue ink on a paper, and it provies a "wet" signature, and can't be mixed up with the photocopies I make.I will also submit a review on the actual pen, but the review of the pen here, under the refills product has to be made. They are outstanding products.

The Jetstream is my favorite pen for quality and comfort but the refills are increasingly hard to get. These efills came without the 'plug' that used to be seated in the top of the tube. I swap the plugs out of the empty tubes but it's a little less convenient than when the refills came with the plugs. I guess it is more sustainable this way - reusing the plugs. It is impossible (at the moment) to find blue ink. I don't know what is going on so I bought all I could find. Maybe the tariffs are interfering with supply.

These are a good value for the product. The Jetstream series is a fantastic pen, they last a long time, and they write well. They're also excellent because for relatively inexpensive pens, you can get good refills for them for a nice price. I wish uni-ball would come out with a larger quantity of product per pack of refill, but otherwise perfect pens.

Great ballpoint. Ultra smooth. I grew up with Parker T-ball Jotters, which were great at the time, but the smoothness of the Jetstream is unmatched in a ballpoint. No clotting around the point either, as can be the case with some ballpoints.

These pen refills are very inconsistent. Sometimes they write very well, sometimes they stop. When it works, it’s very smooth and gives the perfect output between bold and fine without too much smudges.

I love the Jetstream RT ink. I only wish the refills came in .5mm. The Jetstream RT .5mm pens are my favorite ballpoint pens, but I can't by refills for them. So, I buy the .7 (bold) to have, but I have to buy new sets of fine point pens once I get through them.

Refills

I recently order the black refills and was really happy with the purchase and use the pen daily. I decided to order the Blue refills but they are terrible. The ink does not flow smoothly, it keeps skipping-stopping which is really annoying. Contacted the company for tips to fix and got no reply. Missed the return date.

Keeps failing over and over again. Usually dry out 1/2 through a cartridge. The black ones work fine, just the blue are really really bad. Tried contacting Uniball, they were transfering me back and forth between their US and Canada department. Stopped using Uni products.

The ink runs out super quick. And they didn't fit as a refill with the jetstream pens I have. Really frustrated and disappointed.

This product is for Jetstream RT, it should be written in the title. It doesn't fit perfectly with the regular Jetstream, but it will do for now...

I love these pens and it's hard to find the blue ink refills in store. So happy Amazon sells them. Ink writes nicely and doesn't smudge.
