The liquid pencil idea is a good one. In our business we use mechanical pencils on a daily basis and the possibility of having a mechanical pencil that doesn't required manual refills along with the inconvenience of stocking the right leads and having them in the right place when you need them, was appealing.
Unfortunately, the idea could not be followed up by performance with these pens/pencils. The biggest flaw is the nip that lays to the paper does not allow for any kind of angle of application. In other words, in order for the liquid to flow, the pencil must be straight upright or very nearly so to work consistently and smoothly. If you are using this exclusively for writing, you may be able to adapt to the needs of the pencil. But if you are considering using it for any type of sketching or artistic production, you will quickly find the pencil to be non-functional. As an artist, you will find the angle required to activate the flow is too vertical and you will be forced to compensate just to get a reasonable and consistent line weight. In fact, under these conditions, it acts more like a ball point pen that is running out of ink.
It's really too bad since we use Sharpie brand permanent ink pens exclusively so we had high hopes for this product. However, I would not recommend it for the reasons stated.
Remember the EraserMate from the 70's? This is that item reborn. It's advertised as a "pencil" but it's actually a pen with erasable ink. The EraserMate wasn't around long and I don't expect this item to be around long either.
We use pencils and thought a liquid pencil would be great. I am left-handed and have problems with pencil and ink smudging because my hand goes over what has been written. The pencil skipped and did not write smoothly.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
