Using these envelopes is easy. Just put your documents inside and choose the closure type that suits you best. For Self - Seal envelopes, simply peel and seal. For Gummed ones, moisten the strip to close. And Redi - Seal envelopes are ready to seal right away. When using, make sure your items fit well inside to avoid any tearing.
