We have notes on How to use Plotting Triangles in our Nav Blog. There are also several YouTube videos on their use.

Many professional navigators prefer this method as it is typically more accurate than parallel rulers or rolling plotter. They take a bit of practice, but are easily mastered, and then cherished for all such applications.

If other brands are discovered, be sure to compare the thickness. Anything thinner than these are difficult to use underway as we rely on sliding one against the other.
