The high-security seal is disposable and cannot be opened without damage after sealing. The anti-rotation design also prevents tampering during transit. Each item has a unique serial number, making it traceable like an ID card, which is super convenient for customs inspection. It's very easy to use, with sturdy buckles and corrosion-resistant metal material, so it's not afraid of wind or sun. What I'm most satisfied with is its sealing performance; once locked, it fits perfectly, so I no longer have to worry about it coming loose due to rough handling.
