I use these labels in the business sector for many years and can consistently report that this is a very high quality, stable and also very nice-looking from the print image forth CD / DVD labels.
The enclosed in the package fixing means (a kind of "rubber plugs") helps when a paste of silver, so you do not slip and the label can be ideally positioned. It's really easy and just makes a great impression (especially when customers !!).
You can see the labels - alike - it printed by inkjet or laser printer. A free design software, the company Sigel for free on their homepage. And even within the software to select the label is totally simple: Why not use after the type designation Select -> Select in this case simply LA505 and you've got two labels per page that you can customize. The "design" can be saved and easy to be used for future reference again can.
All in all, a great solution to its corporate identity positively evaluate!
