I use these envelopes to mail out index cards. When I got down to half of the box, the envelopes couldn't hold a index card properly. I have to make my own crease to seal the envelope, which leaves a gap of the envelope open - not secure whatsoever. Not to mention, the adhesive sticking to the index card due to the inadequate size of the envelopes. It's so annoying and time consuming to have to fix them. I don't recommend.
