Therefore, I have ordered both, and I can recommend the Scotch Magic for office use without reservation!
+ Almost invisible (you can also copy, without having seen anything about it)
+ Can be written on with pencil (only in some permanent markers extends the color slightly)
+ Scrollability
+ Bonds rarely during rolling, and if they do, you can solve it easily again.
o price (but the competition is not effective), but the quality reasonable.
o "adhesive strength" - when I need more support, I reach continues to Scotch Crystal Clear 600-6 rolls, dimensions: 19 mm x 25 m
Conclusion: I can nachezu unreservedly recommend the Scotch Magic 810. 5 stars!
