The UNI SX-210 and SXN-210 ballpoint pens from the Jetstream line can be described in three words: elegance and writing speed. A new generation of pens with quick-drying ink and an updated writing mechanism. The Uni Jetstream SXN-210 1 mm... pen features a strict and concise design. Its body is completely covered with elastic rubber, and the tip and clip are made of metal. For color identification, tinted rings matching the ink color are used at the base of the push mechanism. The pen writes very smoothly, and the lack of a cap makes it easier to store. Replaceable refills. Ball diameter is 1.0 mm, writing line is 0.45 mm.
