The easy-to-use PET-sized water bottle "SANTECO Ordinary Bottle 550" is small and slim, so it is easy to carry around in a bag. The lid has a silicone strap that is easy to carry, and it is convenient to hook it on your finger or attach a carabiner. Since it is a size that is easy to hold, it is easy to use not only outdoors but also on a daily basis. The main body part is completely rubber-painted, which feels gentle when you hold it and has a non-slip effect, so it fits your hand. The appearance of translucency is also cute and fantastic. Tritan is a highly safe material that does not contain chemical substances such as bisphenol A, which has been pointed out to have an effect on the human body, and is also used in baby bottles and medical devices.
