Questions about Dymo Polyester labels

The «Polyester labels ()» from DYMO are labeling strips, but I couldn't find specific information confirming they are cryogenic labels. Regarding compatibility with the LabelWriter 550, DYMO LabelWriter 550 printers are designed to work exclusively with DYMO-branded labels manufactured after April 2020. If the polyester labels are DYMO-branded and meet this criterion, they should be compatible. However, I recommend checking the packaging for the blue or green color and two black dots next to the barcode to ensure compatibility with the LabelWriter 5 series.
