I ship a few hundred packs a month for eBay sales and always use Dymo original labels with my LabelWriter 4XL just to avoid potential problems . Lately the price premium for a big brand has just gotten silly, so I decided to give it a try and was pleased. They appear to be a bit thinner than branded labels but work well. The print is just as razor sharp, maybe even a little sharper. They are still fairly thick, easy to handle and lay flat on the PE mailboxes. Once applied, they stick well. I like the back of these labels better because they have a line of perforations and the long line of printed labels folds easily in the z-axis so they don't curl or roll off my desk as I work. Even if the price of Dymo labels goes down again, I will probably continue to buy them.
