20oz 不鏽鋼三合一隨行杯 - 黑色

The powder coating gives it a nice grip that doesn't slip in my hand, and my iced coffee stayed cold for hours during a long afternoon meeting. It's also great that one tumbler handles hot coffee, cold drinks, and smoothies without any weird taste transfer.

I've been using this tumbler for my morning commute and the powder coating gives it a nice grip that doesn't slip, plus my coffee still feels hot after two hours.

The double-wall insulation actually keeps my iced tea cold for hours without any condensation on the outside. I also love that I can use it for smoothies or coffee depending on my mood.
