Using these envelopes is a breeze. You don't need to use any moisture to seal them. Simply peel off the tear strip and press to seal. This tear strip also has a great benefit - it keeps the adhesive clean from dust, so you can store these envelopes for a long time without worrying about the adhesive losing its stickiness. The sides of these envelopes can expand, which means you can put bulky items inside, like thick documents or small boxes. Since they're made from 40 lb. paper stock, they're quite durable. When storing, keep them in a dry place to maintain their quality. If you notice any dust on the tear strip, you can gently blow it off before sealing.
