For me all that was not bad at all - I glue the labels on free hand, it works surprisingly well. The adhesive holds wonderful, does not make waves and does not dissolve in the margin. The division on the A4 sheets is exactly as with the colleagues from Zweckform, you can simply continue to use the designs. The labels are laser printer-compatible. Oh, and if you use blanks with monochrome top (ie only silver without special color), also shines through anything.
I am very happy - and for the price the labels are really a bargain.
