How it works:
Pull lower packaging film, then place it on display, smooth (goes great with a beer mat), then remove upper packaging film. If it should have sneaked a speck of dust under the film: film Carefully lift and with a strip of adhesive tape (the adhesive side) take the grain. That goes without residue. Then press sheet again. Finished!
So all in all a great thing, if you work absolutely clean. That in addition to a dust-free work area is (at best a new DIN A4 sheet inferior) also washed and disinfected as possible with alcohol, fat-free hands.
