ボイジャー タンブラー - シグネチャー

I’ve had this tumbler for three weeks now, and the ceramic lining really does keep my coffee tasting fresh—no metallic aftertaste like my old steel one. The double-wall vacuum insulation is no joke, too, since my morning brew is still warm at lunch when I get distracted.

The button lid works perfectly—no leaks even after tossing it in my bag. My coffee stayed hot for a solid four hours, and the ceramic lining really does keep the taste clean, no metallic aftertaste like my old steel mug.

The ceramic lining actually does make a difference—my black coffee tastes clean, not metallic, even after an hour. Only gripe is the push-button lid takes a bit of pressure to open one-handed, but it hasn’t leaked a drop in my bag so far.
