Redi-Seal envelopes
Good quality very convenient and seals very easily. Great not having to moisten the envelope to seal.

Doesn't work with QB checks
Some review said these checks work with QB checks and some said they didn't. They don't work with mine. Too much information shows in the windows.

Horrid bad fit
The fold on the back interferes with the insertion of the folded letter! Difficult to use.

Not the right size for what we needed
The windows on the envelope were not in the right placement for our document so I had to return them.

The best envelopes
I buy every time I need envelopes for my checks. They are very easy to use and I know that my checks are secure when sending through USPS.

Shorter than previous purchases
The same envelopes with the same code number as the previous purchase and an eighth of an inch shorter! Not really the same as having fewer items in a package to reduce costs. Will have to fight muscle memory to fold invoices just right so that all the information is visable.

Worth the cost
These envelopes are just a touch larger than regular check envelopes. This makes it much easier to insert documentation with checks or to use the envelopes with both check stock and regular printed paper like invoices or direct deposit stubs.

Window Placement is Off
I purchased these to use for paychecks and mailing checks out. The windows on these envelopes are about 1/3" too low. I have to fold every check differently to get the addresses to line up in the windows correctly. I wanted self sealing envelopes and this is exactly what I received. I wanted good security non-see through this also fits my needs correctly.
