Quality ParkClaim Form #10 1/2 Envelopes, 1 Window, CMS-1500, Privacy Security Tint, 4-1/2 x 9-1/2 Inches, Gummed, 24 lb White, 500/Box (QUA21432-A)

Exactly what I ordered, delivered days before I expected, and not easily confused with self-sealing envelopes. I don't understand the negative reviews based on not being self-sealing! Nowhere in the description have I found them described as self-sealing. If 9 1/2 x 41/2 HCFA lick'em stick'em envelopes are what you want, purchase these without hesitation.

I had to throw about 150 envelopes away because the boxes they come in are so flimsy. One of boxes broke open in shipping and ruined them. I run these thru a printing press, so they need to be somewhat flat. Most all of the other envelopes that I buy offers either a "HARD BOX or SOFT BOX". I prefer the hard box, because the envelopes are always flat. thx for asking.

Good product at a very good price, which is wonderful for my small business. I will continue to order these envelopes.

The window on the right side is too high for the address to show

good item

Great Product and prices and great service

The item pictured is the self-sealing version of the envelopes. Instead, I received the version you have to lick and stick with a different shape to the flap. Otherwise the item is the same. I won't be buying these from Amazon anymore, they charged me the full price when these are considerably cheaper elsewhere .

These envelopes are good quality and the security tint is effective. I would recommend these envelopes for medical billing to anyone.
