"Excellent quality, fast shipping"
“I ordered 50 cartons of A4 3-part carbonless paper for our accounting forms. The coating is consistent, the sheets don't curl, and the blue image is dark and clear. Shipping from their Dallas warehouse took 2 days. Will definitely reorder.”
— James T. (Senior Buyer, CPA Firm, Chicago)
“Best value carbonless A4 on the market"

“We compared 6 suppliers. Kingcolor had the best price per sheet, and the free sample allowed us to test print quality. The 24h quote saved us a week. Now our go-to supplier.”
— Maria G. (Supply Chain Manager, Office Depot preferred vendor)
“Great custom service and OEM"
“We needed 2-part carbonless with a specific perforation and red numbering. Kingcolor produced the OEM version with our brand in 10 days. The quality is excellent, and communication was smooth despite the time difference.”
— David K. (Product Manager, Forms & Labels Inc.)
“Reliable supplier for medical forms"
“FDA compliance was non-negotiable. Kingcolor provided all certificates and test reports. The paper runs perfectly in our laser printers. We’ve been buying for 18 months without a single quality issue.”
— Dr. Anne W. (Clinical Supply Officer, Florida Health Network)
“They actually stock in the US!”
“Most Chinese suppliers ship from overseas with 3-week lead times. Kingcolor has stock in LA and Dallas. I received my 20 cartons in 2 days. The pricing is still factory-direct. Unbeatable.”
— Steve R. (CEO, Office Supply Co., Texas)
