I had a little work into the dimension and handling, but there are plenty of guides on youtube it. The dimensioning is designed for customs, but there are calculators (1 = 2.54 cm). The aid for envelopes, as well as the Falzstift can be beautiful in the board store, so you can put it down well. If you want to make clean folds for cards, etc. one does not come to pass as a help. The board is also large enough for papers slightly larger than A4.
