I was skeptical about the straws being included without a case, but the tapered base fits my car's cup holder perfectly and the double-wall insulation keeps my coffee hot through an entire morning of classes. The leakproof flip lid has survived being tossed in my backpack more times than I can count

The tapered base fits my car’s cup holder perfectly, which is rare for a tumbler this size. Flip lid hasn’t leaked a drop during my commute, and the double-wall insulation keeps coffee hot for hours. Two straws in the box was a nice bonus.
