Condition and information:
Listed here is the high-precision Rotring Isograph Set made by high-quality German standards which provide for great performance and durability.
The set includes four isograph pens in 0.25mm, 0.35mm, 0.50mm and 0,70 tip line width. The bodies and the caps of the pens are crafted in high-quality plastic material in chocolate brown color, which is thick, durable and scratch protective hence it provides physical protection of the pens. The metal clips feature nice crisp engravings that read “Rotring” and “Germany”.
The pens feature a screw-on cap that closes precisely and the needle of the pen fits perfectly into it which prevents the ink from drying out. Each pen is marked with different color and the size of the tip number so the user can easily differentiate them while working.
The tips are made of stainless steel providing for very high precision and long-lasting writing instruments. The needle tip goes through an opening and when it goes inside it blocks that opening to prevent ink from flowing and when the user presses the pen on the paper it actually pushes the needle back so the opening will open up so the ink can come out.
The pens feature a refillable ink reservoir which is easy to refill and can hold a substantial amount of ink.
These pens are famous for their reliability and simplicity of use and are the perfect choice for all technical drawings and creative illustrations. Suitable to be used on vellum drawing paper, line-board, and tracing paper, creating high precision lines helping architects and artists to capture even the smallest details.
The pens are very easy to disassemble which is why they can be easily cleaned thoroughly and maintained.
The set comes with a 23ml bottle of Isograph drawing ink in black color which features a nice consistency and good easy flow since it has a good viscosity needed in order to freely pass through the microtubes used in ideographs and radiographs. It has high opacity and good adhesion does not smudge when dried and it's waterproof. It comes in an ergonomically shaped tube, which makes it easy to refill all technical instruments.
The set also includes two compass attachments and a pen station for four pens. The pen stations are very convenient to use, all the user needs to do is to place the pen in with slight pressure and the pens will always be ready to be used instantly on the reach of their hand while working. While in the pen station the pens are positioned ideally since the horizontal position and the double seal prevent from drying out of the ink. Another convenient feature of the pen stations is that they can be used separately which means that they can be taken out and placed on a drawing table or board with the help of the double-sided tape which is included with the set.
