I found myself hosting my family for Christmas this year and realized that I didn't have a set of coffee mugs since I normally only need the 3 mugs for myself since my husband doesn't drink coffee. I came across these mugs and I am so happy that I was able to get them and that everyone in my family was able to have hot coffee, even if they wondered away from their mug for a little while. I am a convert too. I now only uses these mugs for my morning cup of coffee!
