クラシックタンブラー用交換用ストローリッド

Twist it on and you can literally turn the tumbler upside down without a drop escaping, which is exactly what I needed for tossing it in my bag. The double-wall insulation on the lid itself is a nice touch too, keeping the top from sweating all over my desk.

The clear flip lid seals tight enough that I’ve tossed the tumbler in my bag sideways without a drop, and it’s way more convenient than unscrewing a cap every time. Snaps on with a satisfying click, too.

The insulated flip lid twists on so securely I can toss my tumbler in my bag without a second thought. And the double-wall insulation actually keeps my coffee hot for hours, which is exactly what I needed.
