Review on Arrow Plastic 00030 Measuring 12 Ounce by Michelle Godinez

Good size, functionally comfortable BUT be it temperature shock or other reasons, after just a few months of use mine is showing 100+ vertical cracks, most at about 2/3 the bowl height but some almost from top to bottom. Some of them can be seen in the photos, but due to their orientation, few of them can be seen in any particular orientation. I estimate a total of over 100 vertical cracks spaced 1/16" to 1/8" around its nominal 10 inch circumference. Heating the water in the microwave is likely the source of the heat stroke that caused the cracks, although this is pure speculation it's the only explanation I can offer. hot water due to use in a microwave oven. So I don't recommend wasting your time and money on this mug, at any cost, and it ranges from a few bucks to a single seller charging a paltry $22 including shipping.
