Durability is paramount: Choose stainless steel or thick-plated (≥0.5 microns) metal chains, avoiding unpainted alloy chains (easily scratched).
Lightweight is essential: Leather or hollow metal chains (30% weight reduction).
Budget considerations: Alloy chain bags average 200-500 RMB, while stainless steel versions cost over 800 RMB (data source: 2023 e-commerce platform statistics).
Chain material can be quickly identified through a magnet test (stainless steel is non-magnetic) and by observing the cut surface (alloy cross-section is grayish-white).
