Excellent quality product!
Worth the extra money to know you can't see through them and they seal well.

Perfectly Good Flat Envelopes
They do exactly what I need them to do. I like the pre-stick closure and the easy-open strip. Good quality and thickness. Good value for the cost and fits as much as any 9x12 envelope would hold.

Good product
Great for the price. A few of the envelopes did not stick well without persistent pressing. However, for the price I would purchase these again and again.

Great value!
I do purchase a lot of office supplies from Amazon for convenience, price and quality. These are great and the adhesive is fresh, sticks well and not fry like past big store experiences

Good quality envelopes for mailing certificate packets
These were the most economically priced, self-seal, sturdy envelopes that I could find for mailing certificate packets across the country. The ability to self-seal them speeds up the process considerably and they formed a consistent, secure seal. The packets ranged from 4 to 34 pages per packet and appear to have held up fine during shipping - no complaints from the recipients.
