The Best Check Envelopes — I Buy Them Over and Over!

STNovember 14, 2025

The Best Check Envelopes — I Buy Them Over and Over! As someone who runs a bookkeeping business, I go through a lot of check envelopes — and these are hands-down the best. I’ve purchased them over and over because the quality is consistently great, the security window lines up perfectly, and they hold up well through mailing and handling. They’re sturdy, professional-looking, and always reliable. If you need envelopes you can count on for business use, these are definitely the ones to get! Read more

Work Great

CustomerJune 21, 2023

We process payroll with Quickbooks. We used to order our envelopes from deluxe because that’s who we order our checks from but prices have gone up and we wanted to see what other options we had. These work perfectly, show up quickly and are 1/2 the price. They’re a littttle tighter than the deluxe envelopes but that’s only noticeable if you’re trying to add something in with the check.

Problem with inserting check in envelope.

Roses28July 12, 2022

Envelope was adhered on one side of the inside, so that inside corner at bottom had to be pried open to fit the check. Once this was done, checks fit perfect. All envelopes in box seem to have this problem. I almost sent it back, but then figured out I could deal with minor adjustment. Otherwise envelopes seem to be good quality & fit my checks well.

perfect fit, good quality.

These fit QB's checks perfectly. The checks don't move around. Easy to close. Can't see the check through the security print. They can be re-opened and re-sealed. Read more

ATL ladyDecember 5, 2023

I use a lot of envelopes for my business and normally purchase from my check supplier. They were out of stock so I chose this product to replace. They have worked great and are a better price than my previous envelopes. Read more
