Fits a standard 12oz coffee!Unlike the 200mL cup which looks great but is unable to hold a standard small 8oz coffee, this one holds exactly a 12oz. It's got detachable silicone seals which makes it easy to clean. It's top drawer dishwasher safe. It's got the Thermos brand quality and keeps my coffee hot for several hours! I love it.

Excellent tumbler. Keeps the heat in. Perfect for my morning coffees. Colours beautiful and made well.
Got this on the Black Friday sales for such a good price. Good brand. Sturdy and no leaks! great for both hot and cold stuff
Excellent mug, no leaks and keeps contents hot for long enough
Very convenient to take to and from work, keeps drinks hot for a few hours and looks professional. However the locking mechanism being inside the lid isn't the best design as your hands get covered in drink when you need to lock/unlock it - this isn't the best thing when you're in public and you can't wash your hands.
Nice product. Quality Thanks
