Note: if the jar is turned upside down liquid can leak from the straw as we don't use valves in our straws so these cups can be used for thicker drinks, ie smoothies. | STRAW STOPPERS: Each of our cups are equipped with silicone straws featuring stoppers, eliminating the hassle of toddlers pulling them out from our tumbler cups.
