### ⭐⭐⭐⭐⭐ Just what I needed for my small business!!
*by I***T on January 21, 2021*

I absolutely love these envelopes. I'm am going into my 2nd year using these envelopes exclusively for my small business payroll. These work great to fit in a letter/ timecard/ notice in with my employee's checks which was a must for me. I also love the flip and seal style of these envelopes. It saves so much time and it's relatively easy to open and re-seal when I forget to add something to the envelope. Before I would have to rip open the envelope, throw it away, and use a new one when this happened. The bottom box is just a hair too large and shows just the very top of the memo line. I hand out the checks individually on payday so that is not a big issue for me. I had previously used an envelope made specifically for QuickBooks checks and I could never fit in anything else with the checks, or it would require me to fold the letter size paper in weird ways. So happy I found these over a year ago.
