Compatible with C-Series/DLX/EZ-LP/ADV LX/Blaster/Del Sol LX - 3370 Perforated Paper Labels (1.15" x 1", 1.5" Core, 4.25" OD) - 12 Rolls/Pack for Barcode Printing & Inventory Labeling

We use these as price-ticket labels at our shops and they work perfectly with the Cognitive thermal printer that we have. These labels are very adhesive and, although they do fade over time, I think that has more to do with the lighting and length of time in the store than it does with the thermal transfer. Great product that works as it should.
