No difference from no-name products

I can not quite understand the enthusiasm of other reviews for these envelopes. To no-name products from the supermarket, I see no difference and this Herlitz envelopes still tend to look relatively quickly crumpled.

There are of pressure-sensitive adhesive Herlitz envelopes (where over the splice a tear-off strip of paper is attached) in packs of 25 pieces, which have a much better quality and can be labeled with printers so much better, but also are considerably more expensive.

These envelopes here are absolutely nothing special and probably run into the same Chinese factory from band like other cheap goods as well.
Although the price-performance ratio, but you should not promise too much anyway.
