The Qwetch Stainless Steel Thermos is ideal for keeping your favorite drinks hot or fresh. This bottle maintains the ideal temperature of your drink: cold for 24 hours and hot for 12 hours. It has a high resistance to shocks and corrosion. Its interior does not contain coating or varnish (unlike aluminum containers), and does not alter the flavor of the content. It is recommended to clean with hot water and soap or baking soda. Allow to dry upside down. Do not put in the microwave, dishwasher, oven or freezer. Clean before each use. Beware of liquids and hot food, they can burn: use the product with caution. Do not fill up to the top, just to the line where the lid starts. Friction, strong impacts and falls can damage the product. When not in use, it should be stored without the cover. It is recommended to transport the bottle with the lid upwards to prevent liquid leakage.
