Not bad, with small weaknesses - certainly not "Premium"

I use these mailers for "Büchersendung Maxi". There are also books to approximately 40 mm thickness inside, however, the thickness is also at the expense of the width due to the design principle.

The processing and optics is OK, the adhesive closure works well.

What I did not like so much:
- The board is relatively thin (much thinner and less robust than the ones we know from Amazon Books broadcasts). If you want to send high-quality books, you must have some bubble wrap to pack in between.
- If the bag is closed with a thicker book, small gaps remain on the side of the opening page, but is probably more of a visual problem.
- On the top Versandtasche a great product label is in the middle wrong stuck with bar codes that can be it can be impossible. So throw away either pocket or abpopeln sticker tedious, then, of course, the top layer of the shipping bag is damaged.
