Vaihtokansi - Campy Ruostumaton Teräs Matkamuki

The slider mechanism is so smooth that I can open it with one hand while driving, and the seal held up perfectly upside down in my bag all morning. My coffee stayed piping hot for the whole commute.

Bought this as a backup for the one I lost, and the slide-close mechanism really does keep everything locked tight in my bag—no drips at all. It fits the 18oz mug perfectly and clicks into place with a satisfying snap.

The slider mechanism is buttery smooth and actually stays put when I shove it in my bag upside down. I’ve tested it with hot coffee in the car and not a single drop escaped, which is more than I can say for my last lid.
