they are envelopes. You put something in rip off the sticky paper seal and mail. Good envelopes.

No more painful tongue paper-cuts!

I have always used gummed envelopes enduring glue taste and tongue paper-cuts until now. These envelopes are great! I only wish they were a little closer in price to the gummed ones.

Doesn't feel secure after you close it

The envelope is secure for not being able to see the contents but it seems way too easy to just reopen the envelope and take contents out.
Amazingly great to put letters or paper in to send in the mail or to put kids field trip money in. There are only two downsides i1- batteries are not included 2-does not come with detailed directions on how to use. But I will give the envelopes 5 stars anyway
