Before shipment, I purposely felt the protective film on the tank body — thick and tight, with three layers repeatedly wrapped around the corners. This film is tear-resistant, moisture-proof, and dust-proof, so it can withstand the jostling of sea freight. The worker said with a smile, “Wrap it securely, and when the customer receives it, it’ll be as shiny as new — that brings us pride.” Small details, but care makes all the difference.
