Ace 再生コルク ガラスカップ

I was skeptical about a glass cup I could actually hold without burning my hand, but the cork sleeve is genuinely comfortable and keeps the heat at bay. The clear glass lets me see my coffee's color just right, and it's already become my go-to for morning refills.

The cork sleeve makes all the difference—my hand doesn't slip even when the glass gets hot from my morning brew. It's become my go-to for slow sipping at my desk.

The glass body is perfectly weighted and the cork sleeve adds just enough grip for a morning commute without feeling bulky. I’ve been using it daily for a week and the natural texture makes my coffee feel more intentional, not just another disposable cup.
