Ozark Trail Drinkware Accessories Tumbler Leakproof Replacement Lid, 30 oz

I like these lids because they fit all of my 30 oz. mugs. They keep my coffee hot. They are a little brittle if they are dropped, or if the mug is knocked onto a hard surface, and they break. Yet it is still a good product.

This top fits perfectly and does a great job of being leak proof for the Ozark thermal mugs sold through Walmart. My only complaint with them is that if you are drinking a cold beverage with ice instead of a hot beverage it's harder to drink. The hole in this lid is much smaller than the one on the lid that comes with the mug.
