Why the name Blue4est®?

On some days, the hills of the Black Forest take on a peculiar, shimmering blue color – which is just as unmistakable and unique as the color of our new Blue4est® thermal paper.

It is this proximity to nature which helps us come up with new products so often – just like the world’s first sustainable thermal paper, Blue4est®.
