DescriptionSpecificationsFrequently Asked Questions
The standard length of a pencil lead is typically around 60 mm. In a conventional pencil, the pencil is only able to clutch the lead core until the last 10 mm. The remaining lead then typically becomes unstable and unusable. This wastes almost 17% of your lead! The Platinum OLEeNU, on the other hand, can clutch a lead core until the very last 0.5 mm! That's an incredibly short piece of lead.

Note: for this mechanism to work and let you use your lead to the very last bit, an additional piece of lead must be loaded in the pencil body.

An ordinary pencil's clutch mechanism has an interspace that causes the lead to become weak and unstable. The OLEeNU addresses the issue of lead breakage through the implementation of four major features:

1. 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 (blue and yellow pictured below) that hold the lead to avoid breakage.

2. Internal spring
An internal spring absorbs shock during writing to decrease lead breakage.

3. Sliding metal tip
The tip features a sliding metal sleeve that moves with the lead to give it extra support.

4. "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.

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.

I'm a big fan of inexpensive pencils that look good, are comfortable to hold, are well made and have an interesting feature which in this case is the generous spring clip. This one gets a check in all columns.
