交換用フタ - Arabica/Jones/Miri トラベルマグ

The slider mechanism is so smooth that I can open it with one thumb while holding my coffee in the other hand, and it’s genuinely sealed shut when I toss the mug in my bag. That patented slider is the whole reason I stopped losing half my drink on the commute.

Finally, a lid that actually stays leak-proof in my bag — I tossed my mug sideways and not a drop came out. The slide-open feels sturdy and clicks into place, so no accidental sips while driving. It's a perfect fit on my Miri 16oz and the easiest replacement I've bought.

The slider mechanism is so smooth and clicks shut with a satisfying snap—I can toss the mug in my bag without a drop leaking. The silicone seal fits the rim tightly, which makes me trust the whole thing way more than the old twist-off lid it replaced.
