Herlitz Envelope DL 00764746 VE100

So I can say that fully meets the upper part of the self-adhesive seal the lower part, so that the envelope can close properly.
IMPORTANT !!! it is important to ensure that these envelopes are not pressure-sensitive adhesive envelopes which over the splice a tear-off strip of paper is attached which possibly leads to better adhere.
For people whom this is important should look for envelopes with such Abreißpapierstreifen
The envelope is thick enough processed that you can not look through it (see text).
Otherwise I am satisfied so far and can not complain.
