This purchase was a sensation! The paper is in perfect white, from the distance barely visible irregularities. The size was perfect for my existing flipchart. When I tried to stick the paper, the next great surprise came: It already holes were punched into the top edge of the paper, so you could just hang the paper. And the same with a whole block, because the paper was ingeniously glued together at the top, but only on an edge. This has the advantage that the individual sheets of paper stick together on the one hand good, on the other hand you can turn over the pages yet. A great innovation! Moreover flipchart blocks of paper have the advantage that they take good due to the hygrophilous characteristics of paper both permanent and water soluble markers and make the writing visible. The associated disadvantage is that although the sides are washable, but after that the blocks are not reusable. So probably conceived by the Product Design forth rather than one-off product. Last but not least came yet another surprise to me: It is to represent an optically perfect square structure, separate the pages of the block using a perforation without scissors with a smooth torn edge! Ingenious, these predetermined tear site was mounted below the above-mentioned suspension holes, so you can leave the block even hanging and yet tear! Conclusion: Thanks to ingenious innovations a really super smart product that has the potential to upset the global flipchart block industry neat!
