Product Description
Koh-I-Noor Rapido Sketch Technical Pen- Size 3x0/.25Once used mainly by the graphic art industry technical pens are making a cross over into fine art. Many of our customers have requested them for pointillism and detailed pen-and-ink artwork. Of course they can still be used for graphic design as well! These pens use the refillable ink system (please see the alternate image to view one of the pens disassembled). The knibs are stainless steel. Each pen comes in a re-useable plastic box and includes a 3/4 ounce bottle of waterproof black ink. Technical pens require special care; the knibs MUST be flushed out with water after every use to ensure that the ink does not dry in the tip. The tips are very delicate; similar to an airbrush tip- they must not be dropped on the floor. Technical pens have to be held upright in order to get proper ink flow. Tipping the pen to the side while working will result in a broken line.

This review is from: Koh-I-Noor Rapido Sketch Technical Pen Size 3x0/.25 (Office Product)
Perfect for a serious artist. Pen showed up promptly and proved to be one of the most reliable technical pens I've ever owned. Despite low price this was Koh-l-noor Rapidograpgh pen which lived up to standard. If one is not familiar with koh-l-noor rapidorgrapgh pens then the included instructions on maintenance would be necessary and cleaning solvent should be purchased at the same time. The best technical pen on the market.

If you don't mind the plastic breaking...buy them,
This review is from: Koh-I-Noor Rapido Sketch Technical Pen Size 3x0/.25 (Office Product)
I've used Koh-I-Noor sets for years, they've always had the same flaw. The flaw is right where the ink cartridge connects to the front of the pen. After only a few months of use, with the pens I use the most, the plastic on the outside where the casing connects to the front of the pen, it expands and cracks outwards and eventually strips and doesn't connect any more.The flaw here is that it's made of a plastic that cannot withstand being tightened and loosened repeatedly. These pens ARE great for artists, I just wish the company would just fix the flaw instead of relying on a flawed design. As the reviewer said above, "Serious Artists should buy these" but I say, Serious Artists SHOULD NOT accept faulty products. I will not buy these pens until the issue has been fixed.
