The innovative ballpoint pens for use in the food and pharmaceutical industries are characterized by their retractable mechanism and comprehensive detectability. Both the barrel and the ink cartridge are fully metal and X-ray detectable, making them an indispensable tool in hygiene-sensitive environments. These pens are made from a specially developed polymer approved for food contact. Their exceptional durability and break resistance minimize the risk of accidental product contamination from foreign bodies in the processing environment. The robust construction of Detectamet's unique detectable polymer ensures that the pen will not break even under heavy use. The ergonomically designed handle provides a secure and comfortable grip in a variety of working environments, making handling easier and increasing efficiency. This combination of safety, functionality and ergonomics makes these pens the safest writing instruments for use in food and pharmaceutical hygiene.
