## Customer Reviews

### ⭐⭐⭐⭐⭐ Love the sticky strip
*by Y***R on 9 October 2024*

These envelopes are perfect cheque sized envelopes for a reasonable price and very happy with not having to lick envelope glue.

### ⭐⭐⭐⭐⭐ Great for quickbooks cheques

Fit quickbook cheques

### ⭐⭐⭐⭐⭐ Perfect size for QuickBook checks
*by M***G on 27 April 2022*

This was my first time ordering these envelopes. My predecessor at work left no instructions on what size/brand to order. These work perfectly with the our QuickBook computer-printed checks that we mail out to vendors. The window openings show our return address and the vendor name/address perfectly, but hide the Memo line where we may have account numbers or notations that we don't want to show.
