Our core product, the 650ML double-layer vacuum bottle, is engineered with practicality, durability, and versatility to meet daily drinking, outdoor travel, office use, and commercial customized demands. Adopting a classic double-layer vacuum insulation structure, this 650ML capacity thermos delivers stable temperature retention performance, distinguishing it from ordinary single-layer water cups on the market. In terms of material configuration, the cup body adopts a premium dual stainless steel structure: the inner liner is made of food-grade 304 stainless steel, which is widely recognized for its anti-corrosion, rust-proof, and high-temperature resistant properties, ensuring safe storage of hot water, tea, coffee, and various daily beverages. The outer layer uses high-quality 201 stainless steel, which effectively enhances the overall structural stability and wear resistance of the cup body, preventing daily scratches, collisions, and deformation during long-term use.

In terms of dimensional and weight parameters, the 650ML vacuum bottle features a compact and portable body size of 7.27.228cm. The square and slender body design balances capacity and portability perfectly, neither being too bulky for daily carrying nor sacrificing storage space. The net weight of the product is 373g, achieving a lightweight design while maintaining structural firmness, which is convenient for users to put it in backpacks, handbags, or car cup holders. In terms of supply advantages, we have a variety of finished styles in stock for the 650ML thermos, covering mainstream aesthetic styles suitable for global markets. Customers can select ready-made styles directly for bulk procurement, which greatly shortens the delivery cycle.

The 650ML double-layer vacuum bottle brings substantial practical benefits to end users and commercial purchasers alike. For individual users, the core advantage lies in its reliable vacuum insulation technology. The double-layer vacuum structure effectively isolates heat conduction, locking the temperature of hot and cold drinks for a long time, adapting to seasonal use throughout the year. The 650ML moderate capacity is the most suitable volume for daily use, which can meet the daily drinking water demand of adults for a single outing or office work, avoiding frequent water refills, and will not cause excessive weight burden due to excessive capacity. The food-grade 304 inner liner ensures zero peculiar smell, no precipitation of harmful substances, and no chemical reaction with acidic or alkaline beverages, fully protecting users’ drinking health.

For bulk purchasers and brand merchants, the product’s benefits are reflected in supply flexibility and market adaptability. A wealth of in-stock styles supports quick order replenishment and small-batch trial sales, helping customers quickly seize market opportunities. The durable 201 outer layer material reduces product damage rates during transportation and daily use, lowering after-sales maintenance costs. Meanwhile, the product’s compliance with LFGB, FDA, and EU testing standards eliminates market access barriers, enabling smooth sales in European, American, and other mainstream overseas markets. Moreover, the customizable attribute of the 650ML thermos greatly improves product market competitiveness.
