[Vacuum insulation, double structure] The vacuum insulated stainless steel thermos structure is excellent at keeping things hot (12 hours) and cold (24 hours), allowing you to maintain the optimum temperature for long periods of time. Heat is not easily transferred to the outside, and condensation is less likely to form even when cold drinks are placed inside, so you don't have to worry about your hands or the table getting wet. Heat retention (6 hours): above 72 degrees, Cold retention (6 hours): below 9 degrees. [2-way: straw or cup] This water bottle can be used in two ways: as a stainless steel bottle with a cup or as a straw-type stainless steel bottle. You can choose to drink from either the straw or the cup depending on your preference and the situation. The straw is made of soft, BPA-free silicone rubber. The cap opens and closes with an easy one-touch open mechanism, and you can suck up water just by pressing the button. It also comes with a locking function to prevent accidental opening and closing, for added peace of mind. When using a cup, simply press the button on the inner cap to pour into the cup and drink. Capacity: 450ml when using the inner cap, 500ml when using the cap unit. [Our patented product - Kaisei] With Kaisei, the straw cap unit can keep drinks hot or cold! When the temperature of the water in a straw equipped with Kaisei exceeds 50 degrees, the temperature detection function activates and closes the straw's opening, preventing water from coming out even when sucked. When the temperature drops below 50 degrees, the straw's opening opens, allowing you to drink smoothly. Because a straw equipped with Kaisei cannot drink hot drinks even when sucked, the straw cap unit can also be used to keep drinks warm. This prevents you from drinking hot drinks without knowing the temperature and burning your throat. With Kaisei, use is safer and easier. [Highly corrosion-resistant stainless steel] The bottle is made of 18-12-Mo stainless steel (SUS316), which has a proven track record in the food and medical fields. SUS316 is a stainless steel that contains 18% Cr and 12% Ni, with molybdenum (Mo) added to further improve its corrosion resistance and pitting corrosion resistance. It is particularly effective against stress corrosion cracking and intergranular corrosion! This stainless steel has even better pitting corrosion resistance than 18-8 stainless steel (SUS304). An environmentally friendly material, it is hygienic and safe to use. [Simple and easy to clean] The simple, leak-proof design makes cleaning extremely easy. The 48mm diameter wide-mouth design allows for easy filling with ice made in a home ice maker. The inner bottle has a super clean finish, improving the smoothness of the inside of the water bottle, making it less susceptible to dirt and odors, while also improving corrosion resistance. Easy to clean, the entire bottle can be washed with just a quick wash. Children's water bottle straw
