Chemex 玻璃咖啡壺蓋

I was worried the glass would let all the heat out, but this actually keeps my morning brew hot for over an hour while I work. The lid sits flush without any rocking, and it wipes clean in a second after I pour.

The fit is so precise it sits snug inside the rim without any wobble, and the glass is thick enough to feel solid while still letting me watch the coffee level. It's become part of my morning ritual now, keeping the brew warm through a second cup without any fuss.

I was worried the glass would feel fragile, but it’s actually got a nice heft to it. Since I’ve started using it, my coffee stays noticeably warmer for the last cup, and the evaporation is practically gone. Exactly what I needed to finish a pot without reheating.
