Double Wall Vacuum Flask

Double-Wall Stainless Steel Construction

The flask uses an SS304 inner wall and an SS201 outer wall, with a vacuum-insulated double-wall structure. This configuration helps reduce heat transfer between the contents and the external environment. Buyers developing hot- and cold-drink collections should request insulation test results before specifying a particular holding time.

550 ml Capacity for Daily Hydration

The 550 ml capacity offers a practical size for carrying water, tea, or other suitable beverages during work, exercise, and travel. Wholesale buyers can assess the capacity alongside the bottle's 240 mm height and listed 377 g weight when planning product positioning and packaging.

PP Lid and Bottle Closure

The lid is made from polypropylene (PP). During sample evaluation, check how the lid fits the bottle body, whether it opens and closes smoothly, and whether the closure meets the intended use requirements. Although the product page lists leak-proof performance, buyers should verify this claim through appropriate testing before using it in marketing materials.

Material Specifications for Product Development

The separate material grades provide a defined starting point for product documentation. Buyers should confirm the final material configuration and any applicable food-contact requirements for their target market before approving a purchase order.

OEM Support for Customized Drinkware

MACYS accepts OEM orders, allowing buyers to discuss branded product development with the manufacturer. Logo placement, surface decoration, color options, and packaging requirements should be reviewed and approved before bulk production.
