Vacuum-Insulated Glitter Rhinestone Flask

This 600ml thermal flask combines functional insulation with distinctive visual design. Built from food-safe 304 stainless steel with a reflective gold finish, it uses double-wall vacuum technology to sustain beverage temperature: hot drinks remain warm for up to 6 hours, cold ones stay chilled for up to 12 hours. Its dimensions (25 cm × 7 cm) and 380g weight support one-handed operation and easy stowing in backpacks or tote bags. The entire body displays uniform rhinestone patterning, while the base incorporates a subtle but effective grooved texture for reliable standing stability. Suitable for tea, coffee, juice, wine or infused water, it's intended for frequent reuse. Maintenance is straightforward — gentle wipe-down or short rinse suffices; submerging decorated sections is not advised to safeguard rhinestone adhesion and metallic sheen.
