Redi-Seal envelopes have pressure-activated latex adhesive on 2 surfaces. Just press together for a strong, durable seal. No paper strips. No moisture required. We promise you won’t miss licking envelopes or those drippy moistener sponges in a cup! Redi-Seal envelopes are the perfect mailroom update for current concerns about surface germs in the workplace. Skip the yuck, save time, and cut waste with every mailing. These self seal envelopes are inkjet printer compatible, though not recommended for the laser printer. (Use address labels instead.) Made of heavyweight 28 lb kraft paper—opaque to protect private contents and durable enough for lots of hard office tasks. Center seams give added strength for heavy contents. Don’t settle for bulky, stuffed #10 envelopes or more expensive oversized flats. Our large envelope can store letter-sized papers flat without ugly folds and creases. This 9" x 12" is the perfect compromise for cost-effective, professional-looking mailings with a little room to spare. Ideal for contracts, catalogs, homeschool assignments, registration packets, large photos, manuscripts and other correspondence. Mail heavy enclosures with confidence. Stock up on boxes for your next bulk mail project! 250 Per box.

Great envelopes. Bought the Amazon brand to save a few dollars but they didn’t work as well as the Quality Park brand. These will be my go to from now on even if they are a little more expensive. Definitely recommend these for alm your mailing needs.

Envelopes are very convenient and perfect size for documents that are not voluminous. I used them to send out corporate tax returns. The self adhesive flaps are very convenient.

I should’ve read the description more closely.... you have to seal these ones yourself & when you do seal it, I recommend taping the envelope as well. Better off getting the pre-sealed envelopes
