The rotring 300 is rotring's entry level pencil in the numbered series of pencils. The next up is the 500, then the best known of the series, the 600 followed by the rapid PRO and then the top of the line 800. At one time, when the pencils were made in Germany there was a 400 and a 700 in the series. However these are no longer produced and fetch a pretty penny when found. The rapid PRO, cost wise, fits in between the 600 and the 800. This sort of fills the gap left by the out of production 700. There does not appear that there is a replacement for the 400.
As far as entry level pencils (ELP) go the rotring 300 is a slightly above average pencil. It features a design that is reminiscent of the 500 and 600 pencils. While the later mentioned 500 and 600 pencils have removable metal grip areas the 300 does not. The body is a single piece made of plastic, only the tip is removable and made of chromed brass and stainless steel. The push button cap is also made of plastic while the removable pocket clip is made of chromed metal. The pencil features a lead grade indicator which is something usually found on higher end pencils. Unlike the 500, 3600 and 800 the lead grade indicator on the 300 is made of plastic, not metal. There is no detent, but there is enough friction to hold the indicator on station during use.
The 300 breaks down into 4 major components: The main body which includes the pocket clip and the internal mechanism; the tip; the eraser and the cap or push button. The internal mechanism at first appears to come out of the body tube but is stopped part way out. The lead reservoir is transparent plastic while the clutch assembly is wrapped in white plastic and adhered to the lead reservoir. There is no clean out rod stuck to the eraser. The plastic cap fits snugly onto the lead reservoir covering the eraser. The lead reservoir has a plug in the top of it with a small hole restricting the flow of lead into the reservoir to a single piece at a time. The eraser is a standard size white vinyl eraser available just about anywhere. It is surrounded by a thin silver tone piece of sheet metal.

The exterior of the 300 is a semi gloss black with red figures on one of the six sides of the body, just under the pocket clip. The grip area is cylindrical and molded to simulate knurling. It is not very sharp but it works because of the pencils very light. The pocket clip is removable, but I would never do so as it has to be pulled over the plastic LGI which is also molded to simulate knurling. The pocket clip would, I'm afraid, ruin the LGI by scratching it or gouging it. The tip is small with not a lot of gripping area. Removing it the first time or later if it had been replaces to tightly, will require the assistance of a rubber jar opener. When replacing it tighten it only enough to keep it on.
Now for some of that dry stuff, the stats. The pencil weighs a mere 8.4 grams, making it a light weight indeed. It is 141 mm long, has a diameter of 9 mm across the flats and has a balance point 72 mm from the tip of the pencil which gives it practically perfect balance. 2 strong presses of the cap expels enough lead to write with. The lead reservoir has room for a full container of lead (12 pieces) but it will have to be fed in one piece at a time. The mechanism is fairly quite due in part to it's almost complete plastic construction. Should you have a lead jam, common with 0.3 mm pencils, you'll have to supply your own clean out rod as the 400 does not come with one.
Being such a light pencil, many will find it an enjoyable experience to write with the 400. I however find it a bit light for my taste. I have to hold the pencil too tightly for extended use which hurts my hand. Holding the pencil higher up at the point where the body meets the grip area helps but when using HB lead the print seems too light. The use of grade B lead will help out also by making a darker impression with less pressure.
Overall I like the look of the 300 as it has the appearance of the beloved 600. The pencil still come in 0.3 mm but for how long as the 600 comes only in 0.5 and 0.7 mm lead sizes. While the extremely light weight of the 300 may be heaven for some users, but not for me. I prefer the feel of the 600 because it has some heft to it.. That said, I think the rotring 300 is a dandy little entry level pencil that offers the user features found in some higher cost pencils without the higher price tag. It's light weight makes it easy to carry in the breast pocket of a shirt without the need of a pocket protector. So if you are in the market for a lightweight 0.3 mm drafting pencil that offers nice features then seriously consider the roting 300.
