28 lb Heavyweight kraft paper keeps contents safe and confidential in transit. Too busy to wet-sponge your way through stacks of waiting mail? Release & Seal envelopes are affordable self-sealing options that don’t require moisture. A peelable paper strip protects the adhesive from dust so your envelopes last longer in storage.

Just peel, press and go. Use 9" x 12" envelopes to fit thick stacks of letter-size papers, legal documents, contracts, catalogs, photos, and other materials you prefer to mail flat without folds. Our 9 x 12 self-sealing stay-flat mailer handles it all! Center-seam catalog-style envelopes open on the short side.

You can drop in contents with ease. Great for sorting paper at the desk, in the classroom or in the file room.
