This sleek Stainless Steel Vacuum Tumbler isn't just stylish – with a clear lid that allows you to see your drink, it's practical for on-the-go hydration. Maintaining cold temperatures for up to 16 hours and hot for up to 8 hours, it's perfect for any adventure. Constructed without BPA and compliant with FDA standards, your safety is as assured as its durability. For long-lasting use, we recommend hand washing over dishwashing and advise against microwaving. Its resemblance to a stemless wine glass adds an elegant touch, yet it's substantially more robust – a safe choice for outdoor events where breakage is a concern. The sturdy build ensures no fuss over damage from drops or during transit.
