I wanted the peel and self-sealing security envelopes (no windows). These have two flaps that you seal together. Does not go into a printer too well. I like to put our address with the logo on our envelopes. I don't like the kind that need to be moistened because of bulk mailings. I wanted a bulk supply of envelopes that work well with printers are self-sealing and with security tint.
This office is a busy contract public defender's office which also handles general practice cases so efficiency quality and cost are equally important. We use Dell and Brother laser printers and these envelopes have performed well in all of our machines.
These do not print well on our laser printers. They get bunched up and the print is distorted by the flaps. These might work on an inkjet type printer but I don't have one here to test them with. The seal on these works good. If you use labels or hand-write envelopes these will work fine.
We are self employed farmers of over 4 000 acres. We have a lot of mailing; these envelopes look very neat and clean when sealed. The security tint is excellent! We held the envelopes up to the light with a very dark printed word on the inside and could not begin to tell where the word was. Also since they are already gummed (our secretary that has Celiac Disease can not lick envelope glue); does not have to comprimise her health or the apperance of the envelopes with tape.
