슬라이드 뚜껑

The thumb-slide mechanism is honestly so smooth that I catch myself flicking it open and closed even when my coffee's finished. It clicks back into place with a reassuring snap, and the angled design makes sipping while driving feel way more natural than any standard lid I've used.

I’m a lefty and was a bit worried about the thumb flick, but it’s actually perfect for my grip. Slides shut tight enough that I’ve tossed it in my bag without a drop.

I was skeptical about how well the slide mechanism would hold up on my daily train commute, but the angled lid clicks back into place with a satisfying snap every single time. The flick-to-open motion is genuinely effortless, even with one hand holding my bag.
