クラシックタンブラー＆スカウトコーヒーマグ用交換用フリップリッド

The flap clicks shut with a satisfying snap, and I've tested it upside down with coffee inside — bone dry every time. My drink stays hot noticeably longer than it did with the old lid, which makes the whole mug usable again.

The flap snaps shut with a satisfying click and actually holds its seal, which is exactly what I needed after my old lid started leaking coffee all over my desk. The double-wall design keeps my tea hot noticeably longer too.

I dropped my old lid one too many times and finally swapped in this one—the double-walled design genuinely keeps my coffee hot through my whole morning commute. The flap seals tight enough that I can toss it in my bag without a single drop escaping.
