I prefer self seal envelopes because they save time and make mailing simpler. I do not have to lick adhesive or use water, which makes the process cleaner and more convenient. In my experience, a good self seal closure also gives me peace of mind that the envelope will stay shut during handling and delivery.
Choosing the Right Size
