不鏽鋼大杯

I was worried 28 ounces might be too big, but it's actually perfect for my long work mornings. The double wall really works—my tea is still pleasantly warm three hours later.

Keeps my coffee hot for hours, which is exactly what I needed for long work days. The 28-ounce capacity means I'm not constantly refilling, and the double-wall design really does prevent any condensation on the outside.

I was a bit skeptical about the double-wall claim, but my coffee stays hot for over two hours. The 28-ounce capacity is perfect for my long mornings. Just remember it's hand wash only.
