With a common MOQ of 1000 pieces, buyers must plan large-volume orders upfront, but the mix of suppliers from South Korea, Austria, and India offers geographic flexibility to balance cost, quality, and logistics. A strong 50% phone-verification rate helps build trust and reduce fraud risks during negotiations, while the wide price range of $1.67–$4.20 per piece means buyers can leverage location-based differences to find the best value without compromising on quality or supply stability.
