all is good
Size: 9 x 12 Inches
does what it's supposed to do, maybe could use a bit more glue on the flap, and paper seems to be on the thin side. But I would buy it again.

Great choice for envelopes

A good-quality product at a good price
Size: 9 x 12 Inches
I've always had good luck with Quality Park stationery items. I'm happy to say that this product is as good as the other Quality Park items I've purchased, the envelopes are made of appropriately strong paper, as stated, and are consistent and well-boxed.

Exactly what I was looking for but the packaging was damaged
Size: 9 x 12 Inches
These came in a box that was absolutely mangled. By some miracle the envelopes were undamaged. They are exactly the right size that I wanted and they weren't very good shape I'm very happy with the order but, I can't believe that they were fine with the condition of the box.

Fast delivery
Size: 9 x 12 Inches
These envelopes were just as I expected. Even though I live in a smaller town, they arrived the next day, and were a few dollars cheaper than Walmart!
