UniJet Stream Prime High Grade multi ballpoint pen 0.7mm 3 colors & Mechanical pencilx3000;0.5mm (Black Red Blue) MSXE4-5000-07 (Black)

As someone who is addicted to writing implements (I can stop buying them any time, right?) I have to say this is, overall, the nicest multipen I've had.It seems well made. The matte finish gives a decent, non-slippery grip. Its metal construction gives it a nice mid-weight, heavier than plastic but not so heavy one would notice it much. Although a bit wider than a stick pen, I find this remarkably slim for a three ink plus pencil combo unit.It uses the standard multi-pen refill, the Type D1. The three included when you buy it are of course Jetstreams. For those not familiar with them, the Jetstream is a hybrid ballpoint; it falls somewhere between the familiar old school ballpoint pen and a gel pen. Jetstreams in particular have a fine reputation as smooth writers. These refills are excellent that way, exhibiting both the Jetstream smoothness and its good line quality, heavier and darker than most ballpoints.Of course a darker line means the ink will be used up sooner. D1 refills don't hold much ink, and Jetstream D1 refills are more expensive than most, so this may be a concern. One could use less expensive, standard ball point D1 refills from any number of other companies if expense is a worry. It is a standard refill type, so there are many brands available.As for the multi-pen itself, it is nicely made. It is mostly metal. The lower barrel rotates reasonably smoothly to switch between the various pens and pencil; not as smoothly as my Zebra Sharbo X, but that only has three units; two pens and one pencil. Didn't come with them either, you had to buy them extra. The Uni comes fully loaded and ready to go.You can change ink colors by turning the lower barrel either way. I had another pen where you could only turn it one way; once you went past blue, for example, the only way to get back to it was to continue all the way around until it came up again. You couldn't turn the pen one notch backward. It's surprising how annoying this gets after a while.Turning the barrel the "wrong way," the direction that would unscrew the barrel so that you can remove it and replace worn-out ballpoints, risks unscrewing the barrel when all you wanted to do was change ink color. However, only the lower three quarters or so of the barrel actually come off when you want to replace refills. There's about an inch wide section, the flared part just below the pen's clip, that doesn't come off. Grip this section when turning the barrel the "wrong way"and it won't unscrew on you.The pen can have a slight rattle when writing, but no worse than I have encountered in ordinary, single color, push button retractable pens.All in all a neat gadget. I like it very much.

Let me begin by saying, I'm a HUGE fan of rollerball pens that don't smudge when writing. So much so, that I actually removed Yhr Monte Blanc Cartridge from my Monte Blanc and used a different cartridge just to experience a rollerball that doesn't smudge.That being said, this is a GREAT pen, at the moment this one has become my daily driver and I absolutely love the pen size, the consistent ink flow, it's comfort and grip size are perfect. To be honest, I am / was a bit astonished by how normally sized the pen was given the fact that it has, Black, Blue, Red, and Pencil options in the one pen. And unlike basically any other multi ink pens, this one is Not Abnormally thick.You won't be displeased by this pen, it's not a cheap pen, but rest assured you get MUCH MUCH more than what you're paying for.

This is an excellent pen. I use all four modes of this pen daily, and it functions exactly as expected.Several areas of this pen have worn away. i.e. the paint has chipped/come off in a few areas. At the seam where the cover for the eraser is, the exposed rim above the selection markers, along the barrel seams, and at the tip of the pen. The metal underneath is a copper color. Personally, I like the appearance, but I have to assume that this was not designed to do this, and some buyers may see this as a flaw.Writing quality is excellent. The duration/writing span of the ink cartridges will depend on how often you use the pen, but they are D1 style refills. I use the pen daily for approximately 1-2 pages worth of writing (black ink) and the cartridge lasts for approximately 1.5 - 2.5 months, and 2.5-4 months for blue and red (based on my writing habits).The ink refills cost you about $3.25+/- $.25 each. You can sometimes find them in bulk on eBay and bring the cost down to $2.40/$2.60 each. The ink is very high quality, but you can get the same ink in disposable pens for about $1.50 each - so don't buy this pen just for the ink. Buy this pen for the ink + its attractive and classic styling "with a twist."Overall, I think this is a great quality pen for a good price. Just keep in mind that it'll cost you $10.00 each time to refill the pen, have extra refills on hand, and the pen will give you a good long service life.
