●Why development? - Many people may want to "use a water bottle every day" for kindergarten, school, work, and outings due to hydration and environmental measures. Happy so that washing such a daily water bottle does not become stressful! It was developed with the aim of washing water bottles. We also recommend the cup and baby bottle. ●Why is dedicated to recommendation - To thoroughly remove grease stains from pots and plates, a detergent with strong detergent is convenient. However, many people may be worried if they take away the moisture on their hands. Soapworks Water Bottle Washing Foam Soap is made of additive-free soap optimized for washing water bottles containing tea and drinks. We also recommend the cup and baby bottle. - It is made of only water and additive-free soap, and there is no fragrance, so there is no such thing as "when you drink tea, the smell of detergent...". It can be washed off quickly, so it saves water. It is recommended not only for water bottles, but also for washing baby bottles and cups. ●Very easy to use! - Press the pump (1~2 pushes) and apply the soap foam directly to the water bottle or cup. Scrub lightly with a sponge and then rinse off with running water. ●Maybe your child will rinse his water bottle and wash it? - Adorable animals are taking a walk with their water bottles in their hands! Washing the water bottle is happy! We offer two types of designs (yellow and ice) with the intention of becoming like this. Children may start washing their own water bottles.
