Tumbler 16 - Ceramic Lined

I was skeptical about the ceramic lining, but my coffee stayed hot for hours without that metallic taste. The 16 oz size is perfect for my morning commute, and it's sturdy enough to toss in my bag.

The ceramic lining actually makes a difference — no metallic aftertaste in my smoothies at all. I filled it with ice water at 8am and there was still ice floating at 3pm.

The ceramic lining is the standout—no metallic aftertaste, just clean coffee flavor that stays hot for hours. The 16 oz size is perfect for my afternoon smoothie too. I've basically stopped using my other cups.
