“We switched to Kingcolor’s 4x6 labels after constant jams with our previous supplier. After 6 months, downtime dropped 80% and we save $12,000 annually on labels. The DDP shipping is a lifesaver.”
“For the price, the quality is unmatched. We resell these labels to over 200 local businesses – zero complaints on adhesion after 2 years. Highly recommend.”

Can I use these labels with my Rollo or Zebra printer without adjustments?
Yes, our 4x6 labels are designed with a 1‑inch core and 4” width that fits most desktop thermal printers. For Rollo, set label size to 4x6 in the driver. For Zebra GK420d, no changes needed. If you use DYMO, we recommend a compatible adapter.
What is the minimum quantity for a custom‑printed label (OEM)?
For custom size, color, or logo printing, the MOQ is 10 rolls (approx. 2,500 labels). Turnaround time is 7–10 business days after sample approval. Custom artwork can be uploaded directly in your account.
How do you ensure the labels won’t fall off in extreme temperatures?
Our permanent acrylic adhesive is tested at -20°C to +60°C and withstands 95% humidity. We also offer a freezer‑grade variant for cold storage. Request a free sample pack to test in your own environment.
What shipping methods do you offer to the USA?
We provide DDP (Delivered Duty Paid) via FedEx or air freight – you pay no extra customs fees. Typical delivery: 5–8 business days air, 12–18 days sea. For urgent orders, we can ship within 24 hours from our Shenzhen warehouse.
Can I get free samples before placing a bulk order?

What is your return/exchange policy for defective labels?
If more than 2% of labels in a batch are defective (adhesion, print quality, or size), we replace the entire order free of charge, including shipping. Our quality guarantee gives you full confidence.
Are these labels BPA‑free and recyclable?
Yes, our direct thermal paper is manufactured without BPA or BPS. The face stock is FSC® certified, and the labels have a silicone release liner that can be recycled through specialized programs. We also offer linerless options upon request.
What is the typical lead time for a first order?
After payment, standard production takes 3–5 days for stock items. For custom orders, add 7 days for design/production. Shipping via DDP air 5–8 days. Total: around 10–14 days door‑to‑door. Rush orders available.
