Thermos Jnl Ultralight Mug 0.35L Thermos Drink Flask Colorful

Hello, New products may sometimes have a slight smell due to production. This can usually be remedied by a good washing with warm water and soap before the first use. Also, all thermoses and water bottles can develop odors if not cleaned regularly. Therefore, it is important to clean it after each use by removing the lid and gaskets, to prevent odor formation. Suitability for School Use: This product is primarily designed to keep hot or cold beverages for a long time as it is essentially a thermos. If your child needs to drink cold water, it is suitable for school use as it will keep the water cool thanks to its thermos feature. However, it may be a little heavier than normal waterers.
