M 시리즈 스테인리스 스틸 캡

Finally, a cap that matches the rest of my bottle without any plastic or rubber taste. The 18/8 steel threads screw on smoothly and it seals tight enough that I can shake my water without a single drip. Exactly what I wanted.

Swapped the plastic cap for this one and my coffee tastes cleaner now — no weird aftertaste after sitting in the bottle all morning. The threading lines up smooth and it hasn't leaked a drop in my bag.

Swapped my old plastic cap for this and the difference is noticeable, the steel stays cold to the touch even after a full day in my bag. Threads on tight with zero drips, which is exactly what I wanted for a bottle I toss around constantly.
