I like this coffee sleeve more than the ones with buttons just out of personal preference. For one thing, I am a klutz. I will scald myself for sure if I have to hold hot coffee while trying to fiddle with buttons on a coffee sleeve. This one slides on just like the cardboard sleeves. It fits the 16 and 20 ounce cups. You just slide it on and then up until it is on the cup snugly, and you are good to go.
Here is the other fabric I have that I am itching to turn into cute little coffee sleeves!
...And lets not forget the hot tea drinkers!!!
