100 9 X 12 Self Seal Security Catalog Envelopes - Designed for Secure Mailing - Securely Holds up to 60 Sheets of Paper with Strong Peel and Seal Flap (100 Envelopes)

I needed envelopes that fit the size of the majority of sewing patterns. I am an online seller and price, quality, as well as fit is always important to me and these envelopes check all the boxes.

The envelopes measure exactly what's advertised, 6"x9". The weight is similar to any descent quality mail envelope. The peel and stick feature is great and the adhesive holds well. If it matters for your use, the inside has a security print pattern to protect privacy of contents from being easily seen. I use these as a cheaper alternative to package vegetable seeds at my store. The factory glued areas hold up to any amount of product I load and never leak from those spots. I have purchased many times and will continue to do so in the future.

Quality large envelopes at a low price. The envelopes have a thickness which provides confidentiality for enclosed documents. My purchase was actually for the 11x14 size which is large enough for letter or legal size documents. With it being so hard to find legal size envelopes in many local stores, the reasonable price, product availability and quick delivery are more reasons why I will be buying these envelopes again in the future.

Exactly as described at an excellent price. Difficult to find the size and color, but easily located and purchased through Amazon!

Bigger than expected. Also it came semi opened and taped.

Using these to mail out items, the sticky stuff is great nice size envelopes and when you write on them, it does or

Light weight! Save on postage

Had to do a big mailer project for work and found these envelopes on Amazon. They are great quality! I was surprised at how thick they were for the price. Printing company was going to charge me an arm and a leg to provide these to me. This is a great value. They are great for everyday mailer things. I mailed out 2 thick 8.5x11" tri-fold brochures in each envelope, it held its shape great and there was no tearing by the time customers got them from what I have heard. Love that they are self adhesive as well, saves me a lot of time. I'd say this is a solid purchase for your mailing projects. White looks more professional than manila ones in my opinion. I will continue to use these for the office.

Better prices if you buy bulk

Be careful to put 'all' papers in the envelope before sealing you can't open it up to reseal it - sticky glue.

Great size for a book. Love it has a peel strip to seal it.

This is a great crisp clean envelope to use for sending out mail

1st time use today - quick seal is thicker adhesive line than previous versions I have purchased. Good 'heavyweight' thickness for mailing. Really happy I decided to try these 9 x 12 envelopes.
