ボイジャー タンブラー - シグネチャー

I’ve had mine for two weeks now and the ceramic lining genuinely keeps my black coffee tasting clean instead of metallic, which was always my biggest gripe with steel tumblers. The vacuum insulation held the heat from my 7 a.m. brew until almost noon, and the push-button lid has survived a few clums

The push-button lid really is leak-proof—I tossed it in my bag sideways with hot coffee and nothing spilled. The ceramic lining is a game changer too; my morning brew tastes clean and fresh, not metallic, and it’s still warm three hours later.

I love that the ceramic lining keeps my black coffee tasting clean and never metallic. The lid seals tight even when it tips over in my bag, and it stays hot for a solid two hours.
