Slight weaknesses show the mounting options for sheets in the workbook:
- The fixing of the cover sheet is understated but the sheet can be solved quite easily.
- The mounting rail inside holding the sheets fixed well, but it is quite cumbersome to get the leaves in the holder. If you have practice something, but this goes well.
- An envelope had an incision in the middle. But I think this should not happen often.
I can issue a buy recommendation for these portfolios.
