I purchased this cartridge for use with the P-Touch labelmaker. They are easy to peel (but cannot be re-positioned easily once you have placed them). The ink also does not rub off of them which makes them more hardy. I purchased them on Amazon at a fraction of what they cost at my local retailer (Office Depot).  The silver with black print makes them a bit fancier than the black on white ones that I have been using.  Perfect for making lavels for files or other household and office items.
