There are a few reasons why these mugs are so popular. Hil-Dee puts a lot of love into each one. While there will sometimes be similarities between designs, it is clear that each one has been crafted by hand. The generous size (holds approx. 14 oz) will contain plenty of your favorite hot beverage and the large, sturdy handle fits any hand size comfortably. Hil-Dee adds a bit of whimsy to the bottom with a short inspirational phrase.
