1 review

  • Perfectly fits at least 60 sheets of standard 8.5'' x 11'' letter paper, with a wide opening that makes it easy to stuff even thick stacks of documents
  • Peel and seal flap makes it simple to close without having to lick or moisten the wide strip of glue, which creates a permanent bond when sealed to keep your important documents secure throughout transit
  • Great for organizing, storing, and mailing personal paperwork, company documents, financials, tax returns, reports and more
  • Thick and sturdy 28 lb white wove paper construction securely holds hefty files during transit – even bulky items such as catalogs or magazines
  • Dark security tint lining keeps your important documents securely concealed, safely guarding sensitive legal, tax, or financial documents from view


Worrying about security and durability are the last things that should be on your mind when it comes to mailing your sensitive and/or official documents. Our 9” x 12” catalog envelopes are equipped with a quick and easy-to-use peel and seal closure, which immediately forms a strong permanent bond. Our thick 28 lb paper is lined with a dark security tint and has been sturdily constructed to ensure that your mail reaches its destination safely, preventing even large documents or magazines from falling out during transit.

From photos, receipts, and keepsake documents to large reports, financials, promotional materials or tax documents, the large size of this envelope makes it ideal for both storage and mailing purposes. Write easily on the blank white surface to identify the contents inside, or affix an adhesive label directly to the outside for postage – knowing that your crisp white mailer is helping put your best foot forward when it comes to looks, without scrimping at all on quality.
