Blue Summit Supplies 500#8 Double Window Security Envelopes, Gummed

Blue Summit Supplies are Awesome! I really don't have time to write reviews - but I love their products. They cost slightly less than their competitors - but I think their quality is slightly better. These are definitely "privacy" envelopes; and they seal securely. I use them for Intuit QuickBooks accounts payable vendor checks. We use the full sheet laser checks; keep the bottom stub for our records - mail the check and the middle stub (which has transaction detail) to the vendor. The QB check fits perfectly into these envelopes - with our name/address showing in the top window; the vendor name/address showing in the bottom window. Before, we bought from a "deluxe" supplier - and the price was almost 3x's as much (and sometimes their envelope window cut off the bottom line - which is a problem because it has the zip code... and sometimes it seemed their envelopes were getting a little "tight" to put my checks into). No problems with Blue Summit!

I had a hard time finding a double window security envelope that was reviewed as working well with checks printed in Sage Accounting. I use Sage 50 Accounting and I can say that these fit my checks perfectly! They are good quality - seal well with our Pitney Bowes mail machine and aren't too thin where you can see thru them. Plus, if you can find them thru Amazon Warehouse, are a bargain. Highly recommend!

As my title says, these envelopes are excellent quality at a good price. I didn't even notice that I had changed from the more expensive ones the check companies sell. I definitely will order these again! (This is in stark contrast to the generic name/address labels I ordered from another company instead of the expensive Avery ones. The generic name/address labels were inexpensive, but poor quality and thus a total waste of money.)

We work A LOT with envelopes in our company. We used to purchase them up to a price of 75USD. But thanks to Blue Summit we were able to cut costs and keep our mail running smoothly and effectively. I really like the product and will probably purchase again.

These serve their purpose, and the price is good, so I wouldn't not recommend them. They are #8 -- smaller than #9 return envelopes and #10 standard business envelopes -- designed to fit Quickbooks voucher checks. The glue adheres well. I prefer gummed envelopes for environmental reasons (less waste, though I don't know how the glue is manufactured). The paper is fairly thin and around the windows is a bit rippled, so I will explore other options, but I would use these again.

I've been using these exact brand and type of envelopes for a mid-sized company for several years, having gone through over 2000 individual envelopes. I can't remember a single instance where one failed, or improperly sealed or had some issue. That's in addition to the great value they provide over more expensive alternatives—which is why they're on my automatic delivery subscription.

As far as envelopes go this are good enough but our Quickbook checks do not fit properly in them.

These envelopes are perfect for my needs. The windows are just right to show the address and return address from my checks printed on Quicken. And they are thick enough that you cannot see throught the envelope to see the other information written on the check. It's a big box and will take me a long time to go through these.

To be used with QB cheques, works great.

These are good but you have to lick them so I don’t recommend them at all !! Next time I will read it properly to make sure they are strip peal envelopes

Simple envelopes that work well with our QuickBooks checks.

Although Quickbooks cheques 'fit' in these envelopes, they are way too big and require taping to keep address in view. Will not purchase again.

Works with Sage 50 cheques
