Ace 再生コルク ガラスカップ

The fact that the cork sleeve can be replaced if it ever wears out is what sold me, and the glass itself feels sturdy enough for daily use. I've already used mine for cold brew and water all week, and it's holding up beautifully.

The cork sleeve keeps it from slipping out of my hand even when it’s wet, and the glass feels sturdy without being heavy. I’ve been using mine every day for a week now, and it still looks brand new despite being tossed in my bag a few times.

I dropped it on the tile floor twice already and the cork sleeve absorbs the impact like a champ, still in one piece. Honestly, the fact that it’s designed to be repaired means I’m not shopping for a replacement every few months.
