I purchased these envelopes and the fit is perfect for our invoices. Easy to seal and a great price! Will definitely buy again!

Bought my first box in May 2022, 500 envelopes. I know some lift and seal envelopes can lose adhesion over time, but I just finished my first box (April 2025) and the last envelope sealed just fine. Hope my second box performs just as well.

Great envelopes

With Costs of supplies out of control, these have been a game changer! They are no different than the $60 check envelopes you will find at Office Depot, and that is with the business discount.

The ones that self adhere without a tape - or the best

Great price.. same envelopes staples sells for $99 for 500. No brainer

Envelopes are good quality.

Works as it should

These envelopes are the perfect size windows to fit quickbooks. They arrived promptly and are strong paper.

I purchase these every so many months for work. We use them for statements they are so easy to use. I highly recommend them. You cant find these at staples anymore.

I bought these for work for mailing checks printed from Quickbooks. They work perfectly and are less than half the cost of the envelopes from Intuit. If your company uses Quickbooks and you mail checks, these are a no brainer, save money without sacrificing quality

Works just as well as the office supply store ones at half the price,

Best envelopes for my QuickBooks invoicing and I've tried several!Get these you cant go wrong!

Sealing adhesive is not very good - flap doesn't seal well. The sides exrend up some and makes it difficult to insert the letter.

I only buy Self sealing envelopes and these 9 are perfect for me and you.

They work fine! Just got mine today and tested them. Others have commented about problems with sticking and size. They're the exact same size as the 9's from a major office supply I've been using for years that just got too expensive at $65 per 500.I was also using a competitors peal-n-seal that went up in price from$43 to $58 per 500 just this year! Same complaints were made by people about that brand as well which I didn't observe or have a problem with, they just got too expensive also.Though I'd give a box of these a try to save $ and see how they hold up. It'll take a while to use them all as I go through about 50/month on average, a little over a box of 500 per year so I'll see how well the glue fairs. Other brand didn't dry out as some said and I doubt these will either. Sure you get a bad one, or even a bad box once in a while. It's happened to me with the major name brand as well! That's no reason to bad mouth the entire line or company. Just file your complaint with the seller and get a replacement, simple! If it continues repeatedly, then bad mouth 'em.Glue doesn't feel real tacky, and yet I was pleasantly surprised when I stuck the flap and then tried to open it. It wouldn't come open without tearing the envelope even though it appeared like it wasn't stuck very well. That and the security pattern works because you can't see what's inside, as it should be. If your that concerned about it, then don't use windowed envelopes! ...Duh.The windows are correct and match my invoices perfectly without needing change as I'd set them up for the other brands I've used in the past. Addresses are centered in the windows right where they should be just as with the other brands after folding horizontally in thirds and stuffing the envelopes! For half the cost of others they're a good replacement! Paper's a 'tad' lighter, but 'not by much' and is negligible IMHO. Standard 8 1/2 by 11 folded in 3rds fits perfectly with just the right amount of spacing. I'm pleased with 'em. ;-)

I got these for the office to put our checks in to mail out. They worked out pretty well. I like that I don't have to lick the flap to seal it. I haven't had one issue about any coming open. I even gave them a little test tug to make sure they are sealed. Will be ordering these again in the future.

The invoiced fit perfectly!

Wasn't sure how these envelopes would really close sounded different?! But so easy they seal perfect, better than most if the peel sticks. Will reorder when needed.

I use this for return envelopes. I love the slit that makes it easy to tear them open.
