Q: May I ask what kind of packaging you use?
A: We use anti-static packaging and shock-resistant packaging.Anti-static packaging: Ensure that the packaging materials used comply with ESD standards, including anti-static bags and foam.Shock-resistant packaging: Use custom foam and sturdy outer boxes to ensure that they can pass through regular transportation tests (such as dropping and vibration).So the goods arrive at your hands in perfect condition.
