Premium 500ml Stainless Steel Vacuum Flask with Advanced Insulation Technology

High-grade 304 stainless steel inner/outer walls ensure durability and rust resistance, while the copper-plated vacuum layer maintains optimal temperature for 12-24 hours (hot/cold). The precision-welded mouthpiece prevents leaks and enables smooth pouring.

Ergonomic design features a non-slip silicone base and one-hand operable push-button lid, ideal for outdoor adventures, office use, or gym hydration. The brushed finish resists fingerprints and scratches.

Seamless laser-welded joints and food-safe double-wall insulation eliminate condensation. Compatible with car cup holders and dishwasher-safe for effortless maintenance.

Exclusive to bulk buyers: customizable branding options available on the matte surface (MOQ applies). Ships in crush-proof packaging with barcode-ready retail display boxes.
