I've heard that if you drink coffee from an Owl mug, it makes you smarter. I tried it, it works. This is a set of 3 Gibson Homes Owl coffee/tea mugs. The larger mug does show a small chip on the rim. The smaller two mugs do not show any chips, scratches on the glazing or any cracks. I personally cleaned and disinfected these for proper use. Dimensions: The larger mug. 5.5"W x 4.5H Dimensions: The smaller two. 4.5"W x 4.5H
