We realize there are many things to consider when choosing a mug. We love Natania Hume's mugs for many reasons. The handle shape is wide, comfortable to hold and has the most subtle groove to rest your thumb. The lip of the mug is perfect and at 4.5" tall by 3"wide these mugs are on the big side- holding about 16 ounces. Blue dusk glaze on white clay. These beauties are dishwasher and microwave safe.
