DescriptionSpecificationsQuestions & Answers
Conventional mechanical pencils are only able to clutch the lead core until the last 10 mm, at which point the lead becomes unstable and falls out. The Platinum OLEeNU, on the other hand, can clutch a lead core until the very last 0.5 mm—a 95% reduction in waste that gives you almost 20% more writing out of a typical 60 mm long lead!

The OLEeNU also utlizes three separate mechanisms to help protects lead from breaking while you use it, for a total of four lead-saving features:

  • OLEeNU Guard—In ordinary mechanical pencils, a gap exists between the mechanism that grasps the lead and the pencil tip, resulting in an unprotected lead piece that is easily broken from pressure or movement. The OLEeNU contains two additional clutch parts that hold the lead to avoid breakage.
  • Internal Spring—An internal spring absorbs shock during writing to decrease lead breakage.
  • Sliding Metal Tip—The tip features a sliding metal sleeve that moves with the lead to give it extra support.
  • "Zero Shin"—Since the clutch of an ordinary mechanical pencil is located a slight distance from the tip, typically around 10-12 mm of lead is left unusable at the end (i.e. lead is too short for the pencil and must be thrown away). The two additional clutch pieces of the OLEeNU allow you to use lead up to 0.5 mm in length.
  • Note: For the pencil to hold the lead to the last 0.5 mm, an additional piece of lead must be loaded in the pencil body.

September 27, 2015
This pencil is inexpensive, nice looking, comfortable to hold, writes well, and does almost everything it claims to do. However, there's one catch, and that's that last 10mm of lead this pencil makes available for use. I find that last segment of lead rolls around in the guide tube, so that I can't keep it sharp. I've gotten used to being able to keep the lead point sharp by turning the pencil in my hand, but I can't do that with this pencil, at least for the last 10mm of lead. When I turn the pencil the lead rolls back to it's previous position as soon as I start writing. This is so annoying to me that I wind up removing the last lead segment in order to keep control of the point sharpness. Doing this defeats the economizing purpose of the design of the pencil, so that there's no reason for preferring this design over a more conventional pencil design. But I'd rather have control of the point sharpness than save the last 10mm of the lead piece. So back to the drawing board for this one, as far as I'm concerned.

This is my new favorite pencil for class! It really does help with lead breakage, which is a problem because nobody likes it when you have to click the pencil over and over to advance the new piece of lead and then have to repeat the annoyance ten minutes later(yes, I take a lot of notes).
Another really great thing about this pencil is that the eraser cap fits on the clip while writing so I don't lose it - I really like that.
Overall, this is a sturdy but light pencil that does what it says it does and I'm glad I ignored other reviews and got it. The only thing I have changed is putting a super cushy grip over the pencil because I hold it so close to the tip that grips that come with the pencil never work for me, however this pencil is slim enough to accommodate that - yay!

Very lightweight, the main feature I was interested in is its ability to use up nearly all of the pencil lead. It doesn't quite have that ability without a trade off, because when the stub gets down to 15mm, it no longer grips the lead, and allows it to spin freely inside the sleeve.
What that means is you'll no longer be able to write with a sharp point, because the lead will always rotate to the bluntest orientation, effectively writing with an ellipse. If you have an unusual grip where you hold the pencil straight up and down, you'll be able to write with a 0.5mm diameter line, where the rotation of the lead isn't a factor.
If you're interested in ultimate conservation, you might put up with the lead rotation, but most people will just choose to eject the last 15mm and go on to the next full stick.
The sleeve retracts as you write, so it can write a fairly long time between advancement clicks, but the sleeve drags on the paper if there's insufficient stickout of the lead.
The interesting feature is that the point is spring loaded, so you can push the sleeve back manually on the paper by pushing down on the tip slightly. The sleeve will retract and the lead will be exposed enough to write unencumbered.
The pencil disassembles easily and fully, in case you get a fragment jammed in the mechanism, so it's a simple process to clear out.
The lead reservoir is pretty narrow, basically the same diameter as an ink pen refill tube, so it won't hold as many as most other pencils.
Unscrew the top from the barrel, and the eraser holder remains with the reservoir tube; pull it off from the tube and the leads can then be refilled.

The tip has to be manually pushed in for pocket storage, not as slick as the Pentel GraphGear 1000, but at least it does retract fully unlike the fixed sleeve types. It's light enough that no damage should result from accidental drops.
The clip is nicely done, with a spring loaded hinge that allows it to clip securely onto very thick objects without having to use your fingers to spread it open; just press on the rear of the clip and it opens up easily to clip on your shirt or notebook.

Bargain price, well worth the price of admission.

I think the breakage prevention works well. I really need this because I like a 3 or 4B lead for my class notes and they break easier.
This pencil also advances lead a lot more quietly than others I've tried, also a must for class!
