【Just Bite the Mouthpiece】 If it's the type that releases water just by biting, it's okay even if you don't have a strong sucking power, making it easy to hydrate! Perfect for sharing water with friends or splashing water on yourself. Also recommended for the elderly. 【Comfort】 Made with flexible and soft material that fits perfectly in your pocket. The flask compresses when you drink, so you don't have to worry about water splashing or shaking. You can also see the exact remaining amount at a glance. 【Materials】 BPA-free, food-grade silicone and durable and flexible TPU (thermoplastic polyurethane) are used. Harmless, odorless, and highly safe. New bottles may have a slight odor. Soaking them in rice wash water, green tea, granulated sugar, or vinegar before first use can help reduce the odor. Washing with baking soda is also recommended. Applicable temperature: 0-40°C. To prevent the mouthpiece from getting dirty, it has a dust cover. --------------------------------------------- ✨Please check my profile♫ Great deals available♡ #milktea's shop list is here ---------------------------------------------- ◎Images are for illustrative purposes Please check the actual product photos in the 2nd-7th images for the product condition. ✎Opened for inspection and photography Thank you for your understanding.
