These are a great fit for the checks I use. They have self adhesive stick strip, so no yucky licking, great quality.

I love these envelopes. I print checks with vouchers through Quickbooks and they fit seemlessly. Such a great product at a cost effective price. Will buy again!!

You can buy these half price of what Quicken QuickBooks charges for their check envelopes. And they work great. They have an adhesive closure so no dry mouth on bill paying day.

Not as thick as some envelopes, but still holds up well for mass mailings. My only issue is it’s sometimes a little cumbersome to put multiple folded pages inside due to the inside edges of the envelope being so narrow. The box they come in is very sturdy and holds up well to shelf storage for extended periods of time. Overall, I highly recommend.

The checks fit perfectly in the envelopes with the windows exactly where they’re supposed to be for QuickBooks checks. I like that there is no extra box inside and that the checks are actually separated at each 100 point. The adhesive works great and the security to not be able to see through is perfect.

Excellent quality. No licking or sponging needed. Perfect for QuickBooks checks. Note: NOT meant for invoices, but if you put an extra fold in the bottom and then trifold it you can make them work.
