Creative Home 16 oz Stainless Steel Travel Mug

While marketed as leak proff, its more leak resistant. The "valve" mechanism isnt as tight as one would want but it will keep you from spilling the majority of the contents. Main construction of this travel mug is very sturdy, considering its stainless steel outside and hard plastic inside. Its comfortable to use although the metal lip needs getting use to. My lid did get a bit loose when it put it on my cut, not sure if its from putting in my back pack or from use, but coffee does seep into the seal so becareful of drips.
