I purchased these as the supposedly "compatible" off brand ones, are not compatible with actual Dymo machines. And that's because Dymo use a DRM system, which by the looks of it, is some form of magnetic ink printed on the back of every label. So, of course Dymo charge more than printer manufactures do for ink, for small rolls of thin card stock. And it is thin. That's probably the worst thing about these, is just how thin the cards are. The off brand ones are marginally thicker and it's noticeable. They feel sturdier. These print nicely, and do what they're supposed to. Marked down due to the rubbish DRM that Dymo use and how thin they are.
