トゥーゴータンブラー 240ml/360ml 蓋 プラグ付

I was worried about leaks, but the plug sits so tightly in the lid that I can toss the tumbler in my bag without a second thought. The silicone rubber seal feels much more durable than I expected for a replacement part.

The silicone seal on this lid set fits so snugly that I’ve stopped worrying about spills in my bag, and the plug twists out easily for quick cleaning. It’s the little upgrade my morning commute needed.

The plug snaps in with a satisfying click and the silicone ring really does keep things spill-free in my bag. I’ve used it daily for two weeks now, and the lid still fits just as snugly as day one.
