Space pens

space pen

— a kind of pens that have a much greater resistance to adverse conditions than conventional models (in fact, they were originally created for space flights). “Space” models are made of durable resistant materials and use special ink, which also stays in the cartridge under a pressure of more than 2 atmospheres. Thanks to this, such pens are able to write in any position, in zero gravity, in severe frost or heat, at an altitude of more than 3 km, on almost any surface and even under the water. The main disadvantages are the price and the need for special consumables.
