I was looking for a regular mug size cup that would keep my coffee warm longer. I often will pour myself a mug of coffee at home and forget about it, and I have to microwave it after it has gotten cold. I was looking for something insulated that would keep my coffee warm but wasn't a huge travel mug size, the 10oz is just that. In addition to that, the first mug that was sent to me was marked as delivered by the carrier, but not delivered to my house, and Avana sent me a brand new cup, no questions asked. Best customer service ever. I will certainly buy again. As a bonus, the Caribbean blue color is gorgeous. I am very happy.
