Direct Thermal Labels Zebra Compatible White 4×8 Shipping Labels – 102mm X 210mm (4″ X 8″) – 250 Labels/Roll (25mm Core)

Yes — these labels are 102 × 210 mm (4″ × 8″) and come on a 25 mm (1″) core, which fits most desktop direct thermal printers that accept 4‑inch media and a 1″ core roll. They’re listed as compatible with brands like Zebra, Toshiba, Citizen and Eltron, and fit models such as Zebra GK420d, GX420d and many others.

The extra length gives you more space for detailed shipping info, including longer addresses, multiple barcodes, customs info or handling instructions — especially useful for larger parcels or freight where a standard 4×6″ label feels cramped.

They’re direct thermal, which means the printer head uses heat to darken the label surface. You don’t need ink, ribbons or toner, which keeps running costs lower and simplifies setup.

In most cases, yes — carriers will accept a shipping label as long as it includes the required barcodes and address fields and is printed at the correct size. Because 4×8″ gives extra room, many shippers use this format for more complex shipping documents — but always check your carrier’s specific label requirements in their shipping portal.

Yes — the labels have a permanent adhesive designed to bond reliably to cardboard boxes, envelopes and poly mailers, so they stay put during normal handling and transit. They’re ideal for warehouse or courier use.

To keep print quality sharp and labels easy to feed in your printer, store unopened rolls in a cool, dry place away from direct sunlight, heat or humidity. Thermal paper can degrade over time if exposed to heat or light, so proper storage helps maintain crisp printing.
