"High-quality stainless steel 316L" The inner cup (inner bottle) is made of high-quality stainless steel 316L, which is gentle on the environment and the body, and the lid is made of food-grade silicone and PP material, and is completely BPA-free. This prevents the harmful effects of chemicals. Stainless steel 316L (SUS316L/Sussan Ichiroquel) is a high-grade stainless steel material commonly used in the jewelry, pharmaceutical, and food industries. SUS316L is more resistant to corrosion than ordinary stainless steel and has excellent corrosion resistance. "Seven-layer vacuum insulation" Seven-layer vacuum insulation technology is designed to maintain the temperature of the internal liquid for a long time. Seven layers of special material are used inside the bottle, and a vacuum layer is sandwiched between them to maximize heat conduction. This structure allows cold drinks to stay cold and hot drinks to stay warm, ensuring a comfortable temperature for long periods of time. ``2-way convenient'' This thermal bottle uses a convenient 2-way design. The tea strainer, straw, and straw cap are integrated into the lid of the cup, allowing you to drink either through a straw or directly by opening your mouth. This makes it convenient to use in various situations in daily life. Additionally, the lid of the cup has a water inlet and is connected to a tea strainer, allowing you to directly pour water or add tea leaves. "Easy to Clean" All parts of this thermal bottle are easily removable, making cleaning very convenient. Since a transparent tea strainer is used, you can check to see if there are any tea leaves left inside, allowing for more thorough cleaning. No residue and can be kept clean at all times.
