How to Identify Genuine Johnson Window Film?
1 Answers
For Johnson window films, the Johnson company provides dealers with film racks. If a store doesn't have the original Johnson film racks, the film might be counterfeit. The warranty card has a serial number that can be verified at the China Building Materials Bureau. The warranty is valid with just the warranty card; no invoice or receipt is required. If the core is blue, it's genuine Johnson film; black cores indicate smuggled or counterfeit goods. Additionally, genuine Johnson films do not have labels.
