The water bottle from A Little Lovely Company is made of stainless steel material that does not break and does not rust over time. Due to its material, it is not affected by acidic drinks like fruit juices, unlike aluminum. Additionally, it is also a thermos that has the ability to maintain the temperature of the liquid for a considerable amount of time, such as in the summer at the beach. It also features a straw for easy and controlled flow when the child drinks. Its material has technology that does not contain the harmful chemical substance BPA, making it safe for liquids.
