Shanghai Wansheng Vacuum Flask Co.,Ltd.

Shanghai Wansheng Vacuum Flask Co., Ltd. has been operating since 1996, giving them long-term experience in manufacturing and supplying vacuum flasks — a key advantage for buyers looking for reliable, consistent quality. Their key products — vacuum flasks, glass, and stainless steel — are in high demand across global markets, especially in the health and lifestyle sectors. Being based in China provides strong access to manufacturing capacity and logistics networks. However, no verification of documents, work email, phone number, or account email is available, which raises concerns about business legitimacy and responsiveness. Buyers should request additional proof of identity and contact details before placing large orders or sharing sensitive requirements. Without verified communication channels, it's harder to confirm real-time availability or respond to urgent inquiries.
