Shanghai Wansheng Vacuum Flask & Vessel Co....

Shanghai Wansheng Vacuum Flask & Vessel Co. offers a clear product range including vacuum flasks, coffee makers, and air tents — ideal for buyers looking for durable, everyday-use items. Being headquartered in China gives access to strong manufacturing capacity and low production costs. The company has been operating since 1997, showing long-term stability and experience in the market. However, no key verification details are confirmed — including work email, phone number, or business documents — which raises concerns about identity and legitimacy. Buyers should request additional proof before placing large orders or sharing sensitive requirements. Without verified contact or documents, it's harder to trust the company's operations or respond to urgent inquiries. A verified account email is missing, which limits buyer confidence in communication reliability. This lack of verification is common among smaller or newer suppliers, but it's a key risk when dealing with international trade.
