These Avery labels are specially designed to coverup anything underneath them. They call this TrueBlock, and if you want to be extra sure that nothing can be seen through the label you put on something then this is valuable. If you don't need this then these labels would be an unnecessary expense in comparison to ordinary mailing labels.
These labels are designed for laser printers, though you could also use them in an inkjet. Just make sure you set the proper template in your word processor before printing. These labels are something that I'll have available whenever I need to re-use a package/shipping envelope that has dark writing on it.
Not much to say here, the product works as advertised. The labels are easy to use, old text covered up is as advertised, and there are plenty of templates to print these out. Easy to use, nice price, great product. What's not to love??? ***** RECOMMENDED
