Staples brand labels work as well as any others I have used and they cost less. They get the job done and are a good value. If you keep them in the plastic liner packaging they last quite a while without drying out.
This product has saved me so much time when mailing out letters to our customers. I personally do not think I have good handwriting so this came in handy for that reason as well.
There is a generous number of sheets (25 to be exact) for a total of 750 labels. That's a good supply for me who uses them for several purposes. Besides using them to mail letters and other correspondence I use this size to label various containers such as shoe boxes. Doing so takes the guess work out of finding items stored within the containers long ago. I also label report folders to show the side I wish to be the front. Too often I open the other end only to find the pages that are affixed to the center facing upside down. Having a label at the front guarantees the pages will face me when the folder opens.
