Good quality envelopes. Othjg to complain about. Color is nice and they come extremely clean and slick. I have thankfully not had any issues with rips so for and adhesive works well thickness is minimal and size is as described. Weight is also quite minimal. It is completely opaque so nothing can be seen through.

I recently purchased the Quality Park 9" x 12" Self-Seal Catalog Envelopes to use for serving defendants with our legal complaints. I must say, these envelopes are of good quality and I have had no issues with them so far. The self-sealing feature is quite convenient and saves me time. Additionally, the size is perfect for our legal documents. However, the only downside is the price. These envelopes are a bit expensive compared to other options on the market. Overall, I am satisfied with the quality of the product and will continue to use them for my legal needs.

Good envelopes. Work as expected. Decent thickness, good adhesive.

very nice quality. I will order from this supplier again.

These envelopes are exactly what I hoped for. I frequently mail large packets like this that are fairly heavy. The self adhesive flap is very convenient in sealing the package. I typically fold them down and add extra packing tape along the sides where I have folded it over. If I weren't folding the envelope over and mailing heavy materials, I don't think this envelope would need much reinforcement with tape. Previously I used recycled envelopes, but these were lower in price and are very good quality. I wouldn't hesitate to recommend these.

I’ve purchased these envelopes for my business, and they have held up great. The price is a great value for what you pay, and the quality is excellent. The adhesive seals well and the paper is thick. I definitely would recommend for any standard letter mail.
