💡 QC Insight for Buyers

Structural damage near hinges is a common “silent killer” in e-commerce furniture shipping. Even if the carton remains intact, the internal inertia can cause wood to split. Beyond adding EPE film, we recommend conducting a random drop test on the actual production batch rather than just a sample, as the wood grain density can vary significantly between batches.
