1925 Mentmore Manufacturing Co introduced the name Platignum, and the slogan 'As good as gold' to reflect the use of stainless steel in pens for the first time. Mentmore were anxious to register the name Platinum, but were unable to do so because it could have contravened the laws of product description - as they existed at that time. To overcome the problem, a company was registered in the name of the "Platignum Pen Company", and products carrying the brand name Platignum were introduced. Platignum were the first company to use injection moulding in the production of their pens.
