If only I had more carefully after a Gram Matura administration researched! So I now hold cards in hands that are of quite thin quality. You should complete a started almost ten years ago learning card box. While the old maps it will have a much more stable feel and after all this time are still almost mack free, the Herlitz already unpacked small creases at the corners and edges and look worn. When working with them quickly further traces are added - a pity!
Who rarely takes the cards in the hand or learn just four weeks targeted for an exam and want to throw away the card after that is at the price certainly happy. For long-term use, however, I will revert to something more stable carton next time.
