E-Collar Technologies Inc. Tumbler Nero 40oz con Cannuccia

I'm on my second week of using this on my commute and it's honestly the first tumbler that's survived my car's cup holder without wobbling. The double wall keeps my coffee hot for hours, and the twist closure on the straw lid means no spills even when I toss it in my bag.

The screw-on lid seals tight enough that I can toss this in my work bag upside down without a single drop leaking, and it still fits perfectly in my car's cup holder. The double-wall vacuum insulation keeps my coffee hot for hours, which is exactly what I needed for long commutes.

I’ve been tossing it in my bag and throwing it in the car cup holder every morning, and the screw-on lid has never once leaked on me. The double-wall vacuum insulation is no joke either—ice is still clinking around hours later, which is exactly what I needed for long commutes.
