[Excellent Heat and Cold Insulation Technology] This lightweight, minimalist water bottle reduces the weight of the cup while retaining heat and cold by 30% more than other products. Even after six hours, the water will remain at a temperature of over 70°C if you pour 99°C hot water into the thermos. Even after six hours, the water will remain at a temperature of below 6°C if you pour 4°C ice water into the thermos. Enjoy a cold drink after a backpacking hike or a hot cup of coffee while camping in the winter. [Ultra-lightweight design] The entire vacuum water bottle weighs approximately 189 grams, making it extremely light and slim—lighter than a cell phone. Even when filled with a large capacity water bottle, it can be carried outdoors without any extra burden. It's perfect for everyday use, such as elderly people taking walks or children commuting to school. [Ergonomic Design] The vacuum insulated flask's mushroom-style cap fits perfectly to the curves of your hand, making it easy to open and close. It also looks simple and elegant on a dining table, coffee table, desk, or office desk. Its lightweight and slim 6.6cm diameter allows it to be held in one hand or placed in a car cup holder for convenient portability and storage. [Fully Sealed Design] Our vacuum water bottle uses professional fully sealed leak-proof technology. Once you fill the bottle with the right amount of water and tighten the cap, it will not leak, no matter how hard you shake it. This water bottle is the perfect shoulder bag companion for baseball or soccer games, and an essential tote bag companion for outdoor activities. [Wide Mouth, Easy to Clean] The thermos comes with a 4.5cm diameter tea funnel, which not only prevents tea bags and ice from slipping out when drinking tea or iced water, but also makes cleaning easy as the tea funnel can be easily unscrewed. It can be used all year round. It makes a great gift for parents, children, relatives, and friends.
