What is the name of the energy company associated with the ballpoint pen?

The energy company associated with the ballpoint pen is known as Red Diamond Energy. This connection stems from the fact that the first commercially successful ballpoint pen was invented by Laszlo Biro, and the ink used in these pens became notably linked with a brand called "Red Diamond." This branding directly influences the association, making it easier for individuals familiar with that specific pen and its marketing to recall the name of the energy company. Other options do not have a widely recognized connection to the development or branding of the ballpoint pen, which is why they do not hold relevance in this context.
